Hi and welcome to the Neil Ashton podcast.

2
00:00:03,019 --> 00:00:03,839
In each episode,

3
00:00:03,849 --> 00:00:07,309
we explained some of the fascinating ways that science and engineering

4
00:00:07,469 --> 00:00:09,159
are changing the world around us.

5
00:00:09,699 --> 00:00:14,170
We talk to leading engineers from elite level sports like cycling and Formula One

6
00:00:14,760 --> 00:00:18,670
to some of the world's top academics to understand how fluid dynamics,

7
00:00:18,680 --> 00:00:21,069
machine learning and supercomputing

8
00:00:21,229 --> 00:00:22,729
are bringing in a new era of discovery.

9
00:00:23,790 --> 00:00:27,149
We also hear some of their life stories, their career advice

10
00:00:27,540 --> 00:00:31,590
and lessons they've learned on the way that I hope will be helpful to you too.

11
00:00:31,959 --> 00:00:34,330
So sit back and enjoy this episode.

12
00:00:39,720 --> 00:00:41,419
Welcome back to the Neil Ashton podcast.

13
00:00:42,360 --> 00:00:45,159
Today's guest is Professor Max Welling,

14
00:00:45,470 --> 00:00:48,020
one of the foremost experts in machine learning.

15
00:00:48,369 --> 00:00:49,750
And I was speaking to him in

16
00:00:49,950 --> 00:00:52,939
this episode about AI for science,

17
00:00:52,950 --> 00:00:55,150
the use of machine learning and AI to

18
00:00:55,159 --> 00:00:57,939
solve some of the biggest challenges in science.

19
00:00:58,080 --> 00:00:59,939
Now, if you're in the machine learning world,

20
00:00:59,950 --> 00:01:02,299
you'll already know who Professor Welling is.

21
00:01:02,509 --> 00:01:04,220
But just in case you're, you're not,

22
00:01:04,230 --> 00:01:08,180
I'll just briefly give his background of why he is such an expert.

23
00:01:08,919 --> 00:01:09,339
Well,

24
00:01:09,349 --> 00:01:12,199
as we actually discussed in the podcast cos I I always like

25
00:01:12,209 --> 00:01:15,019
to ask people about their academic careers and how they got to,

26
00:01:15,029 --> 00:01:16,180
you know, where they got to,

27
00:01:16,540 --> 00:01:20,680
uh, he started off, you know, the, the standard academic track, I guess,

28
00:01:20,690 --> 00:01:22,319
doing a master's and a PhD.

29
00:01:22,709 --> 00:01:25,430
Uh, and then as he said, he actually did many postdocs,

30
00:01:25,580 --> 00:01:27,980
um, moving between different universities.

31
00:01:27,989 --> 00:01:31,519
I, I guess, most notably he was with, um,

32
00:01:31,529 --> 00:01:37,139
Geoffrey Hinton who is seen as the sort of godfather of, um, of AI at U of T.

33
00:01:37,410 --> 00:01:39,110
Uh But then he went over to,

34
00:01:39,120 --> 00:01:43,180
to the US uh to UC Irvine and he started being a professor there.

35
00:01:43,550 --> 00:01:46,830
Um And then he ended up actually going um

36
00:01:46,949 --> 00:01:48,309
and being, being, yeah,

37
00:01:48,319 --> 00:01:50,940
an assistant professor there and then coming back to the University

38
00:01:50,949 --> 00:01:53,809
of Amsterdam to become a professor and he's actually stayed there

39
00:01:53,910 --> 00:01:55,410
uh pretty much ever since.

40
00:01:55,709 --> 00:02:00,669
But one of the interesting thing is that he has taken routes into industry and,

41
00:02:00,680 --> 00:02:01,430
and start ups.

42
00:02:01,440 --> 00:02:03,269
So he was a VP at Qualcomm.

43
00:02:03,870 --> 00:02:07,040
Uh And actually very recently, he was also a VP

44
00:02:07,370 --> 00:02:09,690
and distinguished scientist at Microsoft.

45
00:02:10,050 --> 00:02:16,169
He recently left um that position and to start a new start up called CuspAI,

46
00:02:16,179 --> 00:02:19,970
which is working on machine learning for material discovery.

47
00:02:19,979 --> 00:02:22,100
In, in the topic of carbon capture,

48
00:02:22,460 --> 00:02:25,250
we actually go into what his startup's about what they're doing,

49
00:02:25,259 --> 00:02:26,970
why he's interested in this area.

50
00:02:27,789 --> 00:02:28,149
Um

51
00:02:28,860 --> 00:02:32,279
I probably could spend a long time going through all his achievements.

52
00:02:32,529 --> 00:02:35,020
Um But he, he's one of those people who is,

53
00:02:35,789 --> 00:02:36,399
you know,

54
00:02:36,800 --> 00:02:39,199
at the forefront of, of machine learning.

55
00:02:39,210 --> 00:02:42,039
So he's been the people in charge of all the major conference like

56
00:02:42,289 --> 00:02:44,639
NeurIPS, ICML and ICLR conferences.

57
00:02:44,880 --> 00:02:48,259
Um He has been leading, if people haven't seen that,

58
00:02:48,270 --> 00:02:50,820
I would highly recommend that you do look some of

59
00:02:50,830 --> 00:02:53,949
these workshops on AI for science, uh, particularly at NeurIPS

60
00:02:54,240 --> 00:02:57,960
the past few years. So these bring together all the world leading experts

61
00:02:58,080 --> 00:02:58,759
on,

62
00:02:58,869 --> 00:02:59,320
you know,

63
00:02:59,330 --> 00:03:01,520
uh machine learning and its and its application to

64
00:03:01,529 --> 00:03:04,160
science and bring them all together in workshops that's

65
00:03:04,289 --> 00:03:05,660
has been really good.

66
00:03:06,020 --> 00:03:06,580
Um

67
00:03:06,809 --> 00:03:11,729
And what I like about him is he has that unique experience that we,

68
00:03:11,740 --> 00:03:15,600
that we touch about being not just a pure academic

69
00:03:16,160 --> 00:03:19,309
or being a pure industrialist, but someone who has jumped between.

70
00:03:19,320 --> 00:03:23,559
And I really do believe that that gives him uh somewhat a unique insight

71
00:03:23,860 --> 00:03:25,050
into

72
00:03:25,160 --> 00:03:29,399
not just the science but the practicalities of how do you go about it

73
00:03:29,410 --> 00:03:32,589
and that's exactly what we try and discuss a little bit in this.

74
00:03:32,610 --> 00:03:35,339
We purposely keep it reasonably high level.

75
00:03:35,350 --> 00:03:37,820
So we're not going into the super super details

76
00:03:38,039 --> 00:03:41,440
but rather looking at the the big topics. So for example,

77
00:03:41,720 --> 00:03:43,710
we start off by discussing

78
00:03:44,210 --> 00:03:46,520
data driven versus physics driven approach.

79
00:03:46,529 --> 00:03:49,270
It as in do you need to include the physics,

80
00:03:49,279 --> 00:03:52,630
physical equations into the loss functions into machine learning?

81
00:03:52,639 --> 00:03:54,699
Or can you just let the data do it?

82
00:03:55,259 --> 00:04:00,960
We talk about uh foundational models as in, could you create a foundational model,

83
00:04:00,970 --> 00:04:04,029
the science that you can just use or, or just, or just fine tune.

84
00:04:04,679 --> 00:04:06,929
And then we pivot a little bit and

85
00:04:07,289 --> 00:04:10,119
what I think anyway, at least have some interesting discussions around.

86
00:04:10,130 --> 00:04:11,759
Should you open source

87
00:04:11,899 --> 00:04:15,740
the models and the data? We have a good discussion about the merits of that

88
00:04:16,119 --> 00:04:18,510
um ethical considerations, et cetera.

89
00:04:19,070 --> 00:04:21,850
Uh And then we get into the different mode of operation,

90
00:04:21,858 --> 00:04:24,170
what the advantages of academic industry and start

91
00:04:24,179 --> 00:04:26,179
ups in terms of reaching these benefits.

92
00:04:26,670 --> 00:04:28,649
Um We talk about his start up about

93
00:04:28,769 --> 00:04:29,079
CuspAI

94
00:04:29,200 --> 00:04:31,649
we talk about what they're doing, why he's doing this,

95
00:04:31,660 --> 00:04:34,869
his excitement and motivation to go back to a start up.

96
00:04:35,230 --> 00:04:37,209
We briefly took on some of the funding, you know,

97
00:04:37,220 --> 00:04:41,070
what's it like getting funding from VCs in Europe versus the US?

98
00:04:41,500 --> 00:04:45,239
Uh And then we, we sort of finish a little bit discussing career paths.

99
00:04:45,250 --> 00:04:48,470
He goes into more details about his personal journey

100
00:04:48,640 --> 00:04:52,209
through academia, through industry, his advice for people now.

101
00:04:52,450 --> 00:04:55,380
Uh and finishing really on what his

102
00:04:55,600 --> 00:04:58,500
uh thoughts are on the future of machine

103
00:04:58,510 --> 00:05:00,890
learning and how this could help scientific discovery.

104
00:05:00,899 --> 00:05:04,029
So a pretty wide ranging uh just topic like anything

105
00:05:04,040 --> 00:05:06,089
we probably could have spoke for many more hours.

106
00:05:06,100 --> 00:05:06,399
But

107
00:05:06,559 --> 00:05:11,010
I, I certainly learned a lot through this conversation and I, I hope you enjoy it too.

108
00:05:11,019 --> 00:05:11,450
So

109
00:05:11,630 --> 00:05:15,540
uh sit back and please listen to this episode with Professor Max Welling.

110
00:05:16,260 --> 00:05:17,380
do we start it now?

111
00:05:17,890 --> 00:05:18,350
We have?

112
00:05:18,570 --> 00:05:19,119
All right.

113
00:05:20,359 --> 00:05:20,380
Uh

114
00:05:20,480 --> 00:05:23,429
Yeah. AI for science, I think, um,

115
00:05:23,929 --> 00:05:28,040
is the application of the tools that are being developed in machine learning and AI

116
00:05:28,790 --> 00:05:30,239
um to

117
00:05:31,029 --> 00:05:36,410
basically help the discovery process and the analysis process in the sciences.

118
00:05:37,649 --> 00:05:38,510
Um

119
00:05:38,950 --> 00:05:43,320
The interesting thing is that there's also signs for AI in a way which is

120
00:05:44,239 --> 00:05:45,109
the, you know,

121
00:05:45,510 --> 00:05:49,299
using principles from the sciences and the mathematics

122
00:05:49,980 --> 00:05:53,070
such as um you know, symmetries,

123
00:05:53,309 --> 00:05:57,130
um diffusion processes like thermodynamics

124
00:05:57,589 --> 00:05:59,640
to build better machine learning models.

125
00:05:59,799 --> 00:06:04,190
So this thing actually go goes two ways, the causal direction is going two ways.

126
00:06:05,170 --> 00:06:05,709
Um

127
00:06:06,829 --> 00:06:12,089
Now, what we see is that in the sciences um in in a very broad

128
00:06:12,739 --> 00:06:17,429
spectrum of the science is going all the way from the very small uh you know, PICO

129
00:06:17,529 --> 00:06:18,239
secons

130
00:06:18,970 --> 00:06:19,829
uh femto

131
00:06:20,029 --> 00:06:21,769
meters, which is basically

132
00:06:22,029 --> 00:06:23,470
uh high energy physics

133
00:06:23,779 --> 00:06:27,500
where a lot of machine learning is u used to do data analysis

134
00:06:28,010 --> 00:06:29,149
all the way up.

135
00:06:29,630 --> 00:06:32,339
Uh you know, let's say going through molecules and

136
00:06:33,260 --> 00:06:36,660
liquids and fluids and then all the way to sort of

137
00:06:36,670 --> 00:06:39,760
earth sciences and maybe going all the way up to uh

138
00:06:40,529 --> 00:06:41,450
astronomy

139
00:06:42,589 --> 00:06:47,190
um which is the at the scale of the universe uh machine learning mo um

140
00:06:47,359 --> 00:06:49,809
models and methods are being used to,

141
00:06:50,679 --> 00:06:55,929
yeah, model that particular domain, but also analyze the data better. So

142
00:06:56,269 --> 00:06:57,049
it it

143
00:06:57,220 --> 00:07:02,380
it has been having a huge and very broad impact in the science as I would say,

144
00:07:03,600 --> 00:07:04,739
and how much

145
00:07:05,589 --> 00:07:10,369
overlap is there, would you say between the work and the methods

146
00:07:10,690 --> 00:07:12,089
that have been used

147
00:07:12,269 --> 00:07:14,859
to develop, let's say some of the large language models

148
00:07:15,309 --> 00:07:19,450
and those which are in the sciences, is it a matter of applying the same

149
00:07:19,910 --> 00:07:21,250
tools and technologies?

150
00:07:21,260 --> 00:07:24,529
And it's just essentially a different focus area or do you see that

151
00:07:24,540 --> 00:07:27,549
fundamentally there are differences and new approaches

152
00:07:27,579 --> 00:07:29,450
that are need to be developed.

153
00:07:29,769 --> 00:07:34,989
There's a surprising amount of overlap I would say um which I find interesting.

154
00:07:35,000 --> 00:07:36,350
So the fir the first thing to

155
00:07:36,750 --> 00:07:38,920
say is that even within

156
00:07:39,250 --> 00:07:41,429
this incredibly broad range of

157
00:07:42,089 --> 00:07:45,790
um scientific disciplines, of course, the tools that are being used,

158
00:07:45,799 --> 00:07:49,290
the mathematical tools that are being used are often very similar too.

159
00:07:49,299 --> 00:07:50,369
So you start from

160
00:07:50,679 --> 00:07:51,250
you, you know,

161
00:07:51,260 --> 00:07:53,950
it's either a partial differential equation or

162
00:07:53,959 --> 00:07:57,239
stochastic differential equation or ordinary differential equation.

163
00:07:57,730 --> 00:08:00,649
That's because physics is causal, you know,

164
00:08:00,660 --> 00:08:02,630
you try to predict the future from the past.

165
00:08:03,250 --> 00:08:06,829
Um It's typically continuous but not necessarily, but many, you know,

166
00:08:06,839 --> 00:08:09,709
processes are modeled continuously like fluids

167
00:08:11,820 --> 00:08:12,399
a me

168
00:08:13,230 --> 00:08:17,649
and it's local, which means that you, you typically don't have something at a very

169
00:08:17,820 --> 00:08:19,890
far distant place,

170
00:08:20,190 --> 00:08:22,739
instantaneously impacting things here.

171
00:08:23,209 --> 00:08:28,290
And so these three aspects make the tool set typically quite similar,

172
00:08:28,299 --> 00:08:30,089
even even across all those scales.

173
00:08:31,049 --> 00:08:31,549
Um

174
00:08:31,950 --> 00:08:33,820
So now to the question, um

175
00:08:34,460 --> 00:08:37,840
some of these tools which are being developed for image generation

176
00:08:38,570 --> 00:08:42,010
um perhaps more than for large language models.

177
00:08:42,020 --> 00:08:45,710
So they're actually different tools, although they're all being,

178
00:08:46,650 --> 00:08:47,090
you know,

179
00:08:47,119 --> 00:08:51,510
put in the same bucket typically as generative AI but actually quite different.

180
00:08:52,630 --> 00:08:53,130
Um

181
00:08:54,080 --> 00:08:59,340
But especially the methods that have been used for video and and image generation,

182
00:08:59,349 --> 00:09:00,309
which you can actually

183
00:09:00,539 --> 00:09:03,559
somewhat think of as a physical object with pixels

184
00:09:03,570 --> 00:09:06,780
being microscopic degrees of freedom which have some dynamics.

185
00:09:07,809 --> 00:09:08,309
A me.

186
00:09:08,969 --> 00:09:11,270
So the tools and diffusion models for instance,

187
00:09:11,280 --> 00:09:13,549
which is the method that generates all

188
00:09:13,559 --> 00:09:15,950
these beautiful images and videos these days,

189
00:09:16,849 --> 00:09:18,419
those can be almost

190
00:09:18,799 --> 00:09:21,419
literally used to generate molecules

191
00:09:22,330 --> 00:09:23,479
um and fluids.

192
00:09:24,059 --> 00:09:25,159
So um

193
00:09:25,809 --> 00:09:27,710
maybe not surprising because of fluid,

194
00:09:27,719 --> 00:09:28,979
you can think of it as a sort of a set

195
00:09:28,989 --> 00:09:31,559
of pixels or it's typically modeled as a set of pixels,

196
00:09:31,570 --> 00:09:33,309
you know, it evolves over time as well.

197
00:09:34,190 --> 00:09:37,590
Um For molecules you could argue, you know, those are, you know,

198
00:09:37,820 --> 00:09:41,299
it's more like a graph uh where the nodes are

199
00:09:41,900 --> 00:09:43,169
at certain locations.

200
00:09:43,979 --> 00:09:46,719
Um So maybe they're slightly more surprising,

201
00:09:46,729 --> 00:09:49,169
but it is almost literally the same tools.

202
00:09:49,179 --> 00:09:51,150
In fact, we developed uh

203
00:09:51,469 --> 00:09:52,150
what's called equi

204
00:09:52,359 --> 00:09:55,729
equivariant methods which incorporate the symmetries of the world,

205
00:09:55,739 --> 00:09:57,710
which is that a molecule or an image.

206
00:09:57,719 --> 00:10:00,349
So it may be best for an image if you look at sort of

207
00:10:00,570 --> 00:10:00,580
a

208
00:10:00,989 --> 00:10:02,479
histopathology slide,

209
00:10:02,489 --> 00:10:04,659
which is a slide which has all all these kind

210
00:10:04,669 --> 00:10:07,549
of stain cells in them and some cells might be

211
00:10:08,140 --> 00:10:11,039
uh have a tumor in them and and other ones don't.

212
00:10:11,200 --> 00:10:14,580
And your task is to find the cells which are malignant.

213
00:10:15,349 --> 00:10:15,969
Um

214
00:10:16,359 --> 00:10:16,890
So,

215
00:10:17,400 --> 00:10:20,960
you know, if you turn the slide upside down, you know, you don't even know. Right.

216
00:10:20,969 --> 00:10:23,849
It's just the same set of cells, but this rotate a little bit

217
00:10:24,799 --> 00:10:29,280
and, but a neural network doesn't know that usually. And so we've built models

218
00:10:29,700 --> 00:10:30,479
which were called equi

219
00:10:30,690 --> 00:10:32,719
equivariant models, which build in sort of symmetries.

220
00:10:34,289 --> 00:10:36,890
So for instance, you know, those methods,

221
00:10:36,900 --> 00:10:39,239
these symmetries which we've developed for

222
00:10:39,510 --> 00:10:43,390
fission very naturally also transfer to

223
00:10:44,090 --> 00:10:45,359
but back to physics.

224
00:10:45,369 --> 00:10:49,549
So they came from physics in some sense and we turned them into tools for, for,

225
00:10:49,559 --> 00:10:50,289
for images.

226
00:10:50,299 --> 00:10:53,390
And now, now, now we apply them again to molecules, right?

227
00:10:53,400 --> 00:10:56,200
And so a molecule upside down is the same molecule,

228
00:10:56,210 --> 00:10:58,710
a molecule displaced from here to here is still

229
00:10:58,719 --> 00:11:00,929
the same molecule with the same properties typically.

230
00:11:00,940 --> 00:11:01,270
So

231
00:11:01,630 --> 00:11:04,989
that's why these tools are very useful, you know, across the board.

232
00:11:05,840 --> 00:11:07,739
But one of the um

233
00:11:08,309 --> 00:11:12,219
topics that seemed to be very much an active debate

234
00:11:12,880 --> 00:11:15,359
in at least in the machine learning for

235
00:11:16,419 --> 00:11:19,200
fluid dynamics, which is maybe what I'm most familiar with.

236
00:11:19,210 --> 00:11:19,440
But I,

237
00:11:19,450 --> 00:11:21,549
I'd be keen to get your opinion on this

238
00:11:21,559 --> 00:11:24,340
and more broadly to other scientific disciplines is this

239
00:11:24,679 --> 00:11:27,650
sort of physics driven versus data driven.

240
00:11:28,710 --> 00:11:30,200
I see on one side,

241
00:11:30,330 --> 00:11:34,200
the logical argument there are physics laws surely, you know,

242
00:11:34,210 --> 00:11:36,469
the solutions should bound by them.

243
00:11:37,270 --> 00:11:41,570
But I I saw you gave a talk recently and you were alluding to the idea of

244
00:11:42,250 --> 00:11:45,059
there's a sort of cut off point where if you don't have much data,

245
00:11:45,070 --> 00:11:46,590
maybe it makes sense to use them.

246
00:11:47,340 --> 00:11:51,440
But if you have a lot of data, you may even be constraining the problem and, and,

247
00:11:51,450 --> 00:11:51,989
and solving it.

248
00:11:52,000 --> 00:11:54,640
What, what are your current thoughts on this debate around

249
00:11:54,909 --> 00:11:56,900
physics or data driven approaches?

250
00:11:57,030 --> 00:12:00,900
Yeah, very similar. So I, I'm still, I agree with my older self.

251
00:12:00,909 --> 00:12:03,359
So that's good, at least some level of consistency.

252
00:12:03,809 --> 00:12:04,429
Um

253
00:12:04,849 --> 00:12:07,179
But uh so, for instance, uh you know,

254
00:12:07,190 --> 00:12:11,229
when I was still working at Microsoft with a wonderful team there, um uh

255
00:12:11,840 --> 00:12:13,119
we worked on

256
00:12:13,400 --> 00:12:15,159
models for the atmosphere.

257
00:12:16,070 --> 00:12:20,349
Um And this was recently published as a paper called aurora.

258
00:12:21,179 --> 00:12:21,750
Um

259
00:12:21,960 --> 00:12:25,179
So there, there is a lot of data. So it's like a uh

260
00:12:25,380 --> 00:12:27,229
petabytes of data

261
00:12:28,219 --> 00:12:31,210
for because, you know, we predict the weather every

262
00:12:31,559 --> 00:12:32,109
day,

263
00:12:32,320 --> 00:12:33,210
every hour.

264
00:12:33,219 --> 00:12:37,719
Um and we store all that data and then of course, we know what the actual weather was,

265
00:12:37,729 --> 00:12:38,809
at least we have measurements.

266
00:12:38,820 --> 00:12:39,099
And

267
00:12:39,270 --> 00:12:40,809
so it's a very rich

268
00:12:41,080 --> 00:12:43,650
um and outdated set of data in some sense.

269
00:12:44,359 --> 00:12:46,010
Um in that domain,

270
00:12:47,369 --> 00:12:50,099
you can basically let go of all the laws of physics.

271
00:12:50,109 --> 00:12:53,809
You can just say, let's think of this as a big machine learning problem.

272
00:12:53,820 --> 00:12:55,349
We just try to predict the

273
00:12:55,479 --> 00:12:57,710
state of the atmosphere, you know,

274
00:12:57,909 --> 00:13:00,830
a day ahead, you know, 10 days ahead, whatever, right?

275
00:13:01,690 --> 00:13:02,349
Um

276
00:13:02,809 --> 00:13:05,650
And you can just use your transformers and everything

277
00:13:05,659 --> 00:13:08,090
that you use for image and videos as well.

278
00:13:08,099 --> 00:13:08,570
Um

279
00:13:08,859 --> 00:13:12,830
And that worked really well. In fact, it's, it's basically as good as

280
00:13:13,679 --> 00:13:14,150
a me

281
00:13:14,820 --> 00:13:18,179
numerical soul verse. I should be a bit careful saying that. Um

282
00:13:18,559 --> 00:13:20,200
But it's as good

283
00:13:20,969 --> 00:13:21,789
um

284
00:13:22,140 --> 00:13:26,270
with if, if the, if the prediction stays within, you know, the,

285
00:13:27,020 --> 00:13:31,929
the the sort of the input that it was trained on, if it goes far beyond that,

286
00:13:31,940 --> 00:13:33,640
you have to be much more careful, of course.

287
00:13:34,080 --> 00:13:36,429
But the big advantage is just it's way, way faster.

288
00:13:36,440 --> 00:13:39,979
So it can be up to 10,000 like four orders of magnitudes faster.

289
00:13:41,289 --> 00:13:43,979
Now, there's other domains where

290
00:13:44,159 --> 00:13:47,549
this is much harder where you don't have this huge amount of data in fact.

291
00:13:48,799 --> 00:13:50,219
And in that case, um

292
00:13:50,409 --> 00:13:55,849
you should really build in um the what we call inductive biases

293
00:13:56,210 --> 00:13:58,820
that are coming from the laws of physics.

294
00:13:58,830 --> 00:14:02,299
And, and I've seen some interesting examples where, for instance, we know

295
00:14:02,700 --> 00:14:05,950
the continuity equations should hold typically,

296
00:14:05,960 --> 00:14:09,219
if you write down sort of the Navier–Stokes equations,

297
00:14:09,229 --> 00:14:12,440
many of them have to shape of some kind of continuity equation.

298
00:14:12,450 --> 00:14:12,799
So

299
00:14:12,950 --> 00:14:13,770
that, that's the,

300
00:14:14,200 --> 00:14:17,309
the partial differential equation that describes basically

301
00:14:17,320 --> 00:14:20,030
a velocity field over which the fluid moves

302
00:14:20,549 --> 00:14:24,619
um in three dimensions. And then there's a source term basically which you know,

303
00:14:24,950 --> 00:14:26,619
applies extra forces to that.

304
00:14:27,369 --> 00:14:28,109
And um

305
00:14:29,669 --> 00:14:34,349
and so um sort of if you do it with the transformers, you know, it has to learn all that.

306
00:14:34,750 --> 00:14:37,650
But um it makes a lot of sense to say, well, we know

307
00:14:37,890 --> 00:14:41,080
the world is three dimensional and, and, and it has this sort of,

308
00:14:41,460 --> 00:14:43,260
and we know how fluids move around.

309
00:14:43,270 --> 00:14:47,119
We just may not know precisely what the forces are that, that are acting on them.

310
00:14:47,130 --> 00:14:47,650
And so

311
00:14:48,010 --> 00:14:50,289
we learn the forces we,

312
00:14:50,299 --> 00:14:52,789
but we constrain it to be a fluid that

313
00:14:52,799 --> 00:14:55,390
moves around uh according to the laws of physics.

314
00:14:55,400 --> 00:14:56,169
And there

315
00:14:56,419 --> 00:14:59,409
you know, if you have little data, then that's a very good prior.

316
00:14:59,929 --> 00:15:00,549
Now,

317
00:15:00,719 --> 00:15:03,219
the flip side is there's always a flip side. So

318
00:15:03,559 --> 00:15:04,070
if you,

319
00:15:04,960 --> 00:15:08,539
you know, we don't know the precise laws of physics

320
00:15:08,719 --> 00:15:08,750
at

321
00:15:08,979 --> 00:15:10,510
that scale,

322
00:15:10,979 --> 00:15:14,090
even for the weather, right, we have written down or we,

323
00:15:14,099 --> 00:15:16,599
the demetri ologists have written down and I don't

324
00:15:16,609 --> 00:15:21,460
know order 1020 equations which describe all the complicated interactions

325
00:15:21,909 --> 00:15:24,299
of the, you know, the atmosphere with,

326
00:15:24,640 --> 00:15:26,630
you know, the surface with, you know,

327
00:15:26,640 --> 00:15:29,150
the radiation with chemicals and all these things.

328
00:15:29,159 --> 00:15:32,580
So everything is written down in these equations, but these are approximations.

329
00:15:32,590 --> 00:15:34,059
They are not actually, you know,

330
00:15:34,219 --> 00:15:37,859
we we might know the laws of physics at the very microscopic level,

331
00:15:38,099 --> 00:15:41,719
you know how one atom sort of interacts with another atom using quantum mechanics.

332
00:15:41,729 --> 00:15:43,219
And all that, we, we know it very precise,

333
00:15:43,229 --> 00:15:47,080
but it's completely hopeless to simulate the atmosphere at that level.

334
00:15:47,090 --> 00:15:47,979
So we have to

335
00:15:48,150 --> 00:15:50,789
Coors grain is what we call it. We have to go to a

336
00:15:51,020 --> 00:15:51,960
much more

337
00:15:52,299 --> 00:15:52,859
um

338
00:15:53,500 --> 00:15:56,599
sort of a less precise level of description.

339
00:15:58,070 --> 00:16:04,169
And at that level, things become approximate. And so if you impose more and more

340
00:16:05,000 --> 00:16:07,880
laws of physics, which is, you know, you've approximated

341
00:16:08,260 --> 00:16:11,340
at some point, uh you might have so much data that,

342
00:16:11,500 --> 00:16:14,539
you know, you, you sort of build in a ceiling to this modeling,

343
00:16:14,549 --> 00:16:18,140
you say I want you to fulfill these constraints.

344
00:16:18,510 --> 00:16:21,020
But, but if these constraints are approximations,

345
00:16:21,380 --> 00:16:25,369
um at some point, that means that you cannot get out of that box.

346
00:16:25,609 --> 00:16:28,619
And if you have so much data that the model can actually learn

347
00:16:29,580 --> 00:16:31,530
something that's more precise than that box

348
00:16:31,539 --> 00:16:33,119
than those constraints you're giving it.

349
00:16:33,590 --> 00:16:36,979
Um Then you're constraining the model over constraining the model and that's,

350
00:16:36,989 --> 00:16:37,750
that's hurtful

351
00:16:38,799 --> 00:16:41,510
all of these, at least from what I can see most of us,

352
00:16:41,520 --> 00:16:43,200
when we use a large language model,

353
00:16:43,429 --> 00:16:45,340
we never need to train the model.

354
00:16:45,349 --> 00:16:48,489
We are just doing an inference essentially on a pre trained model,

355
00:16:48,500 --> 00:16:49,679
a foundational model.

356
00:16:49,750 --> 00:16:53,020
And most of us never need to, to train it ourselves.

357
00:16:53,429 --> 00:16:54,219
Whereas

358
00:16:54,630 --> 00:16:57,580
if we take a fluid dynamics or, or a weather problem,

359
00:16:58,849 --> 00:17:04,270
do you think that we will ever be able to get to a truly foundational model which,

360
00:17:04,280 --> 00:17:06,989
which is trained on such massive data that it,

361
00:17:07,000 --> 00:17:11,540
it could work for a plane or a car or a building or the weather could be done in,

362
00:17:12,390 --> 00:17:15,930
you know, different parts of the world or anything or, or is,

363
00:17:16,390 --> 00:17:17,368
is science

364
00:17:18,040 --> 00:17:20,719
a problem that's just much more challenging

365
00:17:20,839 --> 00:17:22,040
than um

366
00:17:22,300 --> 00:17:24,660
than what we've done for the large language models to date.

367
00:17:25,689 --> 00:17:29,260
Yeah, it was a very interesting question, I think on the one.

368
00:17:29,270 --> 00:17:30,920
So to me, this is kind of a,

369
00:17:31,550 --> 00:17:35,050
I think it does make a lot of sense to train a very large foundation model.

370
00:17:35,060 --> 00:17:37,229
And this means plenty of evidence now that

371
00:17:37,439 --> 00:17:41,930
if you collect data from diff from very different domains, different regimes

372
00:17:42,280 --> 00:17:42,849
um

373
00:17:42,949 --> 00:17:46,609
training such a pre training, such a very large foundation model

374
00:17:47,209 --> 00:17:47,780
um

375
00:17:48,000 --> 00:17:49,020
is a huge benefit,

376
00:17:49,030 --> 00:17:50,829
especially if you can then fine tune it

377
00:17:50,839 --> 00:17:52,969
to the particular problem that you're interested in.

378
00:17:52,979 --> 00:17:54,430
So with a little bit of data

379
00:17:54,829 --> 00:17:57,589
and a little bit of fine tuning, you can get a very good model.

380
00:17:57,599 --> 00:17:59,560
So I think that's a paradigm

381
00:17:59,989 --> 00:18:03,349
that has now been established. And I think that's, you know,

382
00:18:03,869 --> 00:18:06,949
I think that that that will just work for the foreseeable future.

383
00:18:07,560 --> 00:18:10,400
Um But there's also this thing that um

384
00:18:11,189 --> 00:18:13,130
which are called the 8020 rule,

385
00:18:13,140 --> 00:18:18,209
which is that it's 80% of getting it right is quite easy,

386
00:18:18,219 --> 00:18:20,670
you can do it with 20% maybe of the effort,

387
00:18:21,089 --> 00:18:24,209
but then the last 20% is incredibly hard.

388
00:18:24,819 --> 00:18:27,880
Um And you may be you may you need a lot more effort, right?

389
00:18:27,890 --> 00:18:31,170
And so I think you can see this very clearly for self driving cars, right?

390
00:18:31,180 --> 00:18:32,400
So in self driving cars,

391
00:18:33,069 --> 00:18:35,969
you know, people get very enthusiastic for the 1st 80%

392
00:18:36,670 --> 00:18:41,089
because, hey, we can drive a car without hands on a, on a street. How wonderful.

393
00:18:41,319 --> 00:18:43,020
And then you realize that to get it

394
00:18:43,209 --> 00:18:45,130
to drive inside Amsterdam,

395
00:18:45,910 --> 00:18:46,900
um, you know,

396
00:18:47,250 --> 00:18:48,920
that's not gonna work with that first,

397
00:18:49,150 --> 00:18:51,420
you know, with this first, you know, model you have.

398
00:18:51,430 --> 00:18:54,680
And so you now need an enormous amount of training, but actually

399
00:18:54,849 --> 00:18:56,589
probably just rules based

400
00:18:57,060 --> 00:18:58,660
methods as well.

401
00:18:58,670 --> 00:19:02,939
You know, to make this thing drive safely inside a complicated city like Amsterdam,

402
00:19:02,949 --> 00:19:04,260
maybe San Francisco works.

403
00:19:04,270 --> 00:19:06,729
I don't know, the streets are all rectangular and everything, but

404
00:19:06,859 --> 00:19:08,880
in Amsterdam it's all big chaos.

405
00:19:09,060 --> 00:19:12,579
Yeah, people run red lights, bikes everywhere, you know,

406
00:19:12,589 --> 00:19:14,420
it's like massively complicated.

407
00:19:15,099 --> 00:19:16,390
Um And so

408
00:19:16,729 --> 00:19:17,640
it will take

409
00:19:18,060 --> 00:19:21,489
80% of the time maybe to get this long till of issues correct.

410
00:19:21,500 --> 00:19:24,349
And this is where humans really are very good somehow,

411
00:19:24,380 --> 00:19:26,369
this has to do with this generalization.

412
00:19:26,579 --> 00:19:29,770
Somehow we do this very naturally and very good.

413
00:19:30,459 --> 00:19:34,359
Now, in large language models, I'm sort of seeing something somewhat similar,

414
00:19:34,369 --> 00:19:34,599
right?

415
00:19:34,609 --> 00:19:35,079
Which is

416
00:19:36,079 --> 00:19:37,130
we can get

417
00:19:37,349 --> 00:19:39,609
amazingly good

418
00:19:39,780 --> 00:19:40,369
at, you know, and,

419
00:19:40,599 --> 00:19:43,540
you know, I didn't predict this to be really honest, you know,

420
00:19:44,729 --> 00:19:47,670
to, to build these, these um these chat bots,

421
00:19:49,359 --> 00:19:52,939
but it is, it is uh perhaps 80% of the way.

422
00:19:53,099 --> 00:19:55,619
Um Now the last 20% is

423
00:19:56,550 --> 00:19:58,000
you should get it such that,

424
00:19:58,640 --> 00:20:01,670
you know, you can't trick it into saying all sorts of rubbish, like, you know,

425
00:20:01,680 --> 00:20:03,829
put glue in your pizza or eat rocks, right?

426
00:20:03,839 --> 00:20:07,060
These are the kind of things that are big tech companies are now

427
00:20:07,280 --> 00:20:10,699
struggling with because, you know, if you put this out there,

428
00:20:10,819 --> 00:20:14,079
people will try to, you know, to game it. Um,

429
00:20:14,459 --> 00:20:16,969
and that's very negative publicity and all that. So,

430
00:20:17,739 --> 00:20:20,959
so this last 20% to make, to make it

431
00:20:21,349 --> 00:20:23,599
really understand common sense.

432
00:20:23,609 --> 00:20:24,520
Um, you know, it's,

433
00:20:24,530 --> 00:20:28,599
it's arguably whether this even can be done by just looking at text, maybe this

434
00:20:28,790 --> 00:20:30,209
needs to be some

435
00:20:30,420 --> 00:20:33,130
system that grows up among humans, you know,

436
00:20:33,140 --> 00:20:34,959
with the body and sort of interact

437
00:20:34,969 --> 00:20:37,239
with humans and understand social interactions and,

438
00:20:38,020 --> 00:20:39,900
you know, ethical rules and all these kinds of things.

439
00:20:39,910 --> 00:20:44,270
Maybe it's just, you can just learn that from text and that last 20% might be very,

440
00:20:44,280 --> 00:20:45,189
very hard.

441
00:20:45,709 --> 00:20:48,430
And so perhaps in, you know, in physics, it's the same, right?

442
00:20:48,439 --> 00:20:51,540
So, you know, you can get it, you can get it right? 80%

443
00:20:51,800 --> 00:20:53,760
and that hopefully is useful.

444
00:20:54,020 --> 00:20:57,550
Um But then how do you protect yourself against that 20%?

445
00:20:57,560 --> 00:21:00,359
You know, an unseen initial condition

446
00:21:00,949 --> 00:21:02,969
with incredibly important

447
00:21:03,260 --> 00:21:08,489
consequences like OK, it might just, we might just get a heat wave, 50

448
00:21:08,819 --> 00:21:10,410
°C, you know, do we,

449
00:21:10,969 --> 00:21:13,130
you know, do we warn the public

450
00:21:13,739 --> 00:21:17,689
um or do we not because we, we don't know precisely what's going on, right? And

451
00:21:18,109 --> 00:21:22,050
that I think is incredibly important to get Right. And we haven't really

452
00:21:22,520 --> 00:21:24,609
get our heads around how to do that.

453
00:21:24,619 --> 00:21:27,369
And I think uncertainty quantification and reliable,

454
00:21:27,380 --> 00:21:29,770
uncertainty quantification is going to be key for that.

455
00:21:31,189 --> 00:21:36,410
Very interesting. I haven't really thought about it that way. It's true. The 8020

456
00:21:37,339 --> 00:21:40,420
and now I think about it, how I use these large language models

457
00:21:40,630 --> 00:21:43,880
is I very rarely take the exact output. It gives me,

458
00:21:44,599 --> 00:21:48,599
I normally will iterate on it, but it enables me to

459
00:21:48,969 --> 00:21:50,380
get somewhere much faster,

460
00:21:51,260 --> 00:21:53,209
I suppose maybe from the physics side,

461
00:21:53,219 --> 00:21:56,180
we're expecting it to get perfect where really maybe our

462
00:21:56,189 --> 00:21:59,689
expectation should be more similar that it gets us someone closer

463
00:22:00,479 --> 00:22:04,189
and maybe then we feed that solution into a traditional solver

464
00:22:04,500 --> 00:22:04,640
precisely

465
00:22:04,900 --> 00:22:05,949
to do the next bit.

466
00:22:06,260 --> 00:22:10,150
Um And its initialization like a smart initialization or something.

467
00:22:10,829 --> 00:22:11,150
Yeah.

468
00:22:11,300 --> 00:22:11,739
Yeah.

469
00:22:12,030 --> 00:22:13,099
But all of this,

470
00:22:13,719 --> 00:22:17,219
I still wonder about the data challenge because it seems

471
00:22:17,459 --> 00:22:20,640
because of the internet and maybe things have been clamped down,

472
00:22:21,359 --> 00:22:26,229
you know, so many images and so many text are publicly available that you can get.

473
00:22:27,040 --> 00:22:29,180
Whereas with science,

474
00:22:29,660 --> 00:22:31,040
it's very rare

475
00:22:31,469 --> 00:22:33,520
to have so much of that data

476
00:22:34,010 --> 00:22:37,829
in the public. To me, most companies have that behind firewalls.

477
00:22:38,390 --> 00:22:40,520
Even people publish papers,

478
00:22:40,530 --> 00:22:43,699
but they very rarely publish the entire data that created it.

479
00:22:44,400 --> 00:22:45,020
So

480
00:22:46,079 --> 00:22:49,180
how can we get around that issue of of the data?

481
00:22:49,520 --> 00:22:53,900
Yeah, that's the absolutely key. So that's the, that's the key for progress I think.

482
00:22:53,910 --> 00:22:54,219
So,

483
00:22:54,609 --> 00:22:54,890
so

484
00:22:55,270 --> 00:22:57,329
you can see that the domains were,

485
00:22:57,890 --> 00:22:58,250
you know,

486
00:22:59,209 --> 00:23:02,089
researchers have managed to do a lot more data sharing

487
00:23:02,099 --> 00:23:05,390
or whether it's just more data available have progressed fast.

488
00:23:05,400 --> 00:23:08,130
Um certainly, you know, with machine learning tools.

489
00:23:08,630 --> 00:23:11,290
Um But for many other domains,

490
00:23:11,300 --> 00:23:14,160
uh companies are hoarding that data or even universities

491
00:23:14,170 --> 00:23:16,829
are hoarding their data because it's expensive to generate

492
00:23:17,300 --> 00:23:21,800
and they want to, you know, milk that cow for a couple of years in terms of papers

493
00:23:21,949 --> 00:23:24,069
before they give it to others. Um

494
00:23:24,300 --> 00:23:26,750
And so that is really um

495
00:23:27,160 --> 00:23:29,099
slowing down science and progress.

496
00:23:29,900 --> 00:23:32,719
Um There is, there is great initiatives where,

497
00:23:33,030 --> 00:23:37,219
you know, for instance, in, in bio where people aren't sharing a lot of data,

498
00:23:37,229 --> 00:23:39,739
there is a lot of omics, data available, et cetera.

499
00:23:39,750 --> 00:23:40,060
So

500
00:23:40,510 --> 00:23:42,180
there's, there's also good examples,

501
00:23:42,189 --> 00:23:44,079
there's some materials project for instance,

502
00:23:44,089 --> 00:23:47,959
and other materials projects um around the world where

503
00:23:48,119 --> 00:23:50,280
data about materials are being collected.

504
00:23:50,900 --> 00:23:51,449
Um

505
00:23:51,609 --> 00:23:52,119
But

506
00:23:52,459 --> 00:23:57,520
um I think in the end, we will have to invent the technology that makes data sharing

507
00:23:58,599 --> 00:23:59,219
much

508
00:23:59,670 --> 00:24:05,520
easier. And, and I, you know, would envision some kind of marketplace um where

509
00:24:05,760 --> 00:24:07,420
people have their data

510
00:24:07,719 --> 00:24:09,060
behind a firewall.

511
00:24:09,579 --> 00:24:11,180
Um But um

512
00:24:11,500 --> 00:24:14,300
if I want to train a model, I just go to your,

513
00:24:14,310 --> 00:24:18,099
your data source and I'm going to say um I'm gonna pay you

514
00:24:18,619 --> 00:24:20,160
whatever amount of money

515
00:24:20,849 --> 00:24:22,680
to access your data source.

516
00:24:23,000 --> 00:24:23,979
Now, um

517
00:24:24,920 --> 00:24:26,920
note that I will do it in a differentially

518
00:24:26,930 --> 00:24:30,709
privacy private way which is which is to guarantee that

519
00:24:31,280 --> 00:24:33,520
I'm gonna update my model parameters,

520
00:24:33,530 --> 00:24:36,900
but I'm gonna do it in such a way that I can never reconstruct data

521
00:24:38,079 --> 00:24:39,089
that were, that were,

522
00:24:39,250 --> 00:24:41,859
that were used inside your data source to,

523
00:24:41,979 --> 00:24:45,209
to build my model now, that can be guaranteed.

524
00:24:45,219 --> 00:24:47,459
But that technology also needs to be improved.

525
00:24:48,219 --> 00:24:49,839
So that means that, you know,

526
00:24:51,229 --> 00:24:54,890
you know, your agent and my agent, they negotiate a bit about the price

527
00:24:55,390 --> 00:25:00,089
and then I enter, you know, do my model updating and then I move to the next uh

528
00:25:00,390 --> 00:25:01,709
you know, data source, right?

529
00:25:01,969 --> 00:25:04,530
So now we can train really excellent models.

530
00:25:04,540 --> 00:25:08,500
Um but you know, there is kind of trading going on about how much that is worth.

531
00:25:08,510 --> 00:25:11,199
In fact, you could do it for your own data. So I could say

532
00:25:11,510 --> 00:25:15,569
I've collected all my data over my lifetime, including my medical data, whatever

533
00:25:16,099 --> 00:25:20,910
I'm, I'm quite happy to help that, that hospital, let's say for free.

534
00:25:20,920 --> 00:25:24,089
Um But when Google knocks on my door, I want money

535
00:25:24,459 --> 00:25:26,260
because I want a fair share, right?

536
00:25:26,270 --> 00:25:30,729
And so basically this means or actually for, for open AI kind of, you know,

537
00:25:30,739 --> 00:25:32,199
ChatGPT models, right?

538
00:25:32,209 --> 00:25:32,770
Just like

539
00:25:33,170 --> 00:25:36,560
they now sort of there's lawsuits now, right? So basically,

540
00:25:37,060 --> 00:25:40,160
you know, it's unclear, you know, what these models like, you know,

541
00:25:40,170 --> 00:25:41,810
let's so I think there's a recent

542
00:25:42,050 --> 00:25:46,339
lawsuit against some of these companies that generate songs from, you know, from

543
00:25:46,660 --> 00:25:46,939
different

544
00:25:47,050 --> 00:25:49,180
rights from songs that are being created by artists.

545
00:25:49,189 --> 00:25:51,359
And so these artists feel, you know,

546
00:25:51,829 --> 00:25:54,270
I've created this content and as being, you know,

547
00:25:54,280 --> 00:25:58,619
and somebody else runs away with it and it's, and you know, where am I in this process?

548
00:25:58,800 --> 00:26:01,589
This is a fundamental problem that we have to solve now.

549
00:26:01,989 --> 00:26:06,369
And it would be much better if an artist, you know, or a person who collects data

550
00:26:06,469 --> 00:26:09,170
in any way or generates content or data

551
00:26:09,780 --> 00:26:13,160
gets paid in a, in a reasonable way or can choose

552
00:26:13,979 --> 00:26:17,099
to make their data available to somebody who

553
00:26:17,109 --> 00:26:18,910
wants that data to train their models on.

554
00:26:19,069 --> 00:26:22,869
This is a fundamental problem across the whole machine learning.

555
00:26:23,680 --> 00:26:26,469
And AI think that space that needs to be solved.

556
00:26:27,250 --> 00:26:28,819
That's fascinating. I

557
00:26:30,229 --> 00:26:33,630
it seems very interesting and maybe complimentary but

558
00:26:33,640 --> 00:26:35,660
in some ways also at odds in that,

559
00:26:36,300 --> 00:26:37,270
on one hand,

560
00:26:37,890 --> 00:26:40,189
there is a movement of open source

561
00:26:40,900 --> 00:26:41,920
open data,

562
00:26:42,219 --> 00:26:43,160
open source.

563
00:26:43,170 --> 00:26:46,959
So the idea being that everybody should make their data sets available.

564
00:26:48,069 --> 00:26:48,750
But

565
00:26:49,069 --> 00:26:51,729
and I believe that some of the um

566
00:26:51,920 --> 00:26:54,770
weather forecasting companies who released those

567
00:26:54,780 --> 00:26:57,170
data sets are now debating whether the next

568
00:26:57,579 --> 00:26:59,449
data should be closed

569
00:26:59,689 --> 00:27:00,489
and not open

570
00:27:01,199 --> 00:27:02,089
because

571
00:27:02,579 --> 00:27:05,959
it's true that many companies in our published models have have, you know,

572
00:27:05,969 --> 00:27:08,910
great success, but the people who generate the data have no

573
00:27:09,160 --> 00:27:11,290
financial reward for that.

574
00:27:11,989 --> 00:27:12,489
Um

575
00:27:13,449 --> 00:27:15,650
And I feel that for the sciences,

576
00:27:15,709 --> 00:27:19,910
particularly most applications of science get into industrial use

577
00:27:20,530 --> 00:27:22,989
where there is a commercial side to it.

578
00:27:24,069 --> 00:27:26,609
So just saying open source your data, well,

579
00:27:26,969 --> 00:27:29,030
they're probably not gonna open up their data.

580
00:27:29,180 --> 00:27:30,829
So that's a very interesting point about it.

581
00:27:31,670 --> 00:27:32,390
A way of

582
00:27:33,339 --> 00:27:35,150
a way of people sharing their data

583
00:27:35,670 --> 00:27:37,170
but also being able to make

584
00:27:37,459 --> 00:27:39,479
money and privacy

585
00:27:40,439 --> 00:27:44,520
because I can't see a way of, let's say fluid dynamics. Why would Boeing

586
00:27:44,770 --> 00:27:47,699
release all the aircraft data for train?

587
00:27:47,709 --> 00:27:49,619
Why would Airbus, why would anybody else do it?

588
00:27:50,849 --> 00:27:52,540
It's a competitive advantage,

589
00:27:53,420 --> 00:27:56,469
it's a competitive advantage, which is why I'm always wondering

590
00:27:57,869 --> 00:28:00,810
and then universities typically do more fundamental problems.

591
00:28:00,819 --> 00:28:02,959
So if you train the data on just university data,

592
00:28:02,969 --> 00:28:05,739
it's only gonna work the simple test cases because

593
00:28:06,040 --> 00:28:07,920
universities are incentivized to publish

594
00:28:08,540 --> 00:28:11,430
pure research, typically not full aircrafts.

595
00:28:11,869 --> 00:28:12,520
Um

596
00:28:13,489 --> 00:28:13,619
Yeah,

597
00:28:14,640 --> 00:28:18,349
I think the Blockchain could play an interesting role here somehow, right? So

598
00:28:18,599 --> 00:28:18,810
you,

599
00:28:18,819 --> 00:28:21,510
you could imagine that you could sort of ii I

600
00:28:21,520 --> 00:28:24,530
believe there should be some kind of marketplace for data.

601
00:28:24,750 --> 00:28:26,560
So first of all, we have to realize that

602
00:28:26,660 --> 00:28:29,170
data is perhaps the most important,

603
00:28:30,040 --> 00:28:30,410
you know,

604
00:28:31,449 --> 00:28:32,510
uh what do you say,

605
00:28:32,689 --> 00:28:33,910
resource?

606
00:28:34,530 --> 00:28:38,410
You know, it's, it's kind of the the the the new oil on which these machines,

607
00:28:38,719 --> 00:28:39,150
you know,

608
00:28:39,400 --> 00:28:42,790
and compute, I guess, right? So it's, it's computing and data

609
00:28:43,099 --> 00:28:44,989
that these machine learning methods need

610
00:28:45,329 --> 00:28:47,709
and we just need to put a real value on it.

611
00:28:47,719 --> 00:28:52,390
We have to say, you know, it's, it is valuable if you share your data or give your data

612
00:28:52,780 --> 00:28:55,310
just pushing people to put it open source

613
00:28:55,660 --> 00:28:56,229
is

614
00:28:57,420 --> 00:29:00,670
I don't think it's gonna happen because everybody will always,

615
00:29:00,930 --> 00:29:01,160
you know,

616
00:29:01,170 --> 00:29:04,959
do what's good for them and we just need to make the incentive structures correct.

617
00:29:04,969 --> 00:29:06,069
I think that's the thing.

618
00:29:06,079 --> 00:29:09,130
You don't force people to do things to make the incentive structures correct. So

619
00:29:09,290 --> 00:29:11,530
people who are open sourcing their data probably,

620
00:29:11,920 --> 00:29:12,109
you know,

621
00:29:12,119 --> 00:29:14,260
they work at universities or they work at companies

622
00:29:14,270 --> 00:29:16,680
and then the open sourcing works for them somehow

623
00:29:16,949 --> 00:29:21,000
anyway, because even companies who are open sourcing their stuff probably do it

624
00:29:21,920 --> 00:29:25,099
because in the long run, it will benefit them as well.

625
00:29:26,300 --> 00:29:29,640
What is your general opinion of that open source though? Versus close source?

626
00:29:29,650 --> 00:29:32,800
It seems to be a bit of a debate in the community of

627
00:29:33,560 --> 00:29:37,020
it. Does it help science to open source? But then

628
00:29:37,219 --> 00:29:40,060
how do companies fund themselves if everything's open

629
00:29:40,069 --> 00:29:41,839
source and how easily it can be copied?

630
00:29:41,849 --> 00:29:42,439
Do you have a, a

631
00:29:42,880 --> 00:29:43,739
thought on the,

632
00:29:44,140 --> 00:29:47,609
the optimum approach that you've seen different companies over the years

633
00:29:48,439 --> 00:29:49,510
take? Um

634
00:29:50,310 --> 00:29:52,979
I mean, are you open to talking about open sourcing data or open

635
00:29:53,109 --> 00:29:54,140
sourcing their models

636
00:29:54,390 --> 00:29:55,609
models more?

637
00:29:55,619 --> 00:29:58,449
But yes, I guess also, well, we maybe we just discussed the data,

638
00:29:58,459 --> 00:30:00,150
but how about the models themselves?

639
00:30:00,530 --> 00:30:04,449
I guess the discussion is about whether it's dangerous to release a model,

640
00:30:04,790 --> 00:30:08,250
right? Um Because the, the model can be used for

641
00:30:09,010 --> 00:30:09,349
at the

642
00:30:09,589 --> 00:30:11,949
zeal purposes and is being used for a zeal

643
00:30:12,170 --> 00:30:16,229
purposes. You have, you know, you have to be careful that if you enable

644
00:30:16,739 --> 00:30:20,219
bad agents um to do horrible things.

645
00:30:20,229 --> 00:30:22,609
You know, you, you just have to really think about that. So,

646
00:30:23,099 --> 00:30:26,550
in other words, um if I would have the recipe

647
00:30:27,459 --> 00:30:29,319
to build in a lab,

648
00:30:29,739 --> 00:30:34,959
um you know, a terrible disease that can be, you know, unleashed on the world.

649
00:30:35,479 --> 00:30:38,680
I'm not going to argue for open sourcing that knowledge, you know, clearly,

650
00:30:38,689 --> 00:30:41,270
I just don't want that to be open out there.

651
00:30:41,949 --> 00:30:45,680
Um And so you could argue similar things will apply at some point

652
00:30:46,079 --> 00:30:49,619
to machine learning models or actually maybe already, I mean, at some, you know,

653
00:30:49,630 --> 00:30:51,319
these models can be used for

654
00:30:51,810 --> 00:30:54,339
fishing attacks and all these kinds of things, right?

655
00:30:54,349 --> 00:30:57,750
So, so, or, or crime where you sort of um uh

656
00:30:58,459 --> 00:30:59,739
basically uh

657
00:30:59,910 --> 00:31:03,790
imitate somebody's voice and then you, you ask them to,

658
00:31:03,989 --> 00:31:07,589
you know, pretend to be your son and then, you know, ask to,

659
00:31:08,300 --> 00:31:09,150
to, um

660
00:31:09,310 --> 00:31:10,670
give some money. So

661
00:31:10,910 --> 00:31:13,670
you have to be extremely careful about,

662
00:31:14,400 --> 00:31:14,660
you know,

663
00:31:14,670 --> 00:31:16,750
when you open source something and maybe there just needs

664
00:31:16,760 --> 00:31:20,010
to be some kind of ethical board that decides whether

665
00:31:20,819 --> 00:31:20,829
a

666
00:31:20,949 --> 00:31:25,280
particular very powerful technology can be open source, yes or no.

667
00:31:25,410 --> 00:31:30,079
Now, within that, you know, once, you know, if you're within those bounds of safety,

668
00:31:30,520 --> 00:31:31,280
um

669
00:31:31,550 --> 00:31:34,319
it's up to everyone to open source.

670
00:31:34,329 --> 00:31:37,439
It's, you know, it's a com you cannot tell a company to open source or not. Right.

671
00:31:37,449 --> 00:31:38,010
It's like it's,

672
00:31:38,130 --> 00:31:41,119
I think it's, it's not, not a very meaningful question to say

673
00:31:41,369 --> 00:31:43,680
companies should open source their stuff. It doesn't

674
00:31:44,189 --> 00:31:47,900
because of course they won't if it doesn't, you know, improve their bottom line.

675
00:31:48,410 --> 00:31:53,780
Um So it's up to them to open source, whatever they need to open or want to open source.

676
00:31:54,099 --> 00:31:55,160
But maybe a

677
00:31:55,369 --> 00:31:57,150
more specific question then

678
00:31:58,599 --> 00:31:59,550
is there a

679
00:32:00,010 --> 00:32:02,300
can methods move faster

680
00:32:02,599 --> 00:32:04,959
that have been open source because essentially

681
00:32:04,969 --> 00:32:08,579
you're outsourcing the development to a community effort

682
00:32:09,280 --> 00:32:10,060
or

683
00:32:11,160 --> 00:32:12,500
is it the case that

684
00:32:13,540 --> 00:32:14,630
that sounds nice,

685
00:32:14,640 --> 00:32:16,489
but you can actually move faster by having

686
00:32:16,500 --> 00:32:19,479
an internal team with their own developers?

687
00:32:21,140 --> 00:32:21,349
Yeah.

688
00:32:22,459 --> 00:32:24,270
Yeah. So um so I think

689
00:32:24,670 --> 00:32:26,930
thinking very hard about the incentive structure.

690
00:32:26,939 --> 00:32:30,449
So if, if it's true that if you're a whole number of small play, you know,

691
00:32:30,459 --> 00:32:32,900
a small player cannot compete with a big player, right?

692
00:32:32,910 --> 00:32:36,170
So it does make a lot of sense to put a whole bunch of small players

693
00:32:36,380 --> 00:32:37,229
in a group,

694
00:32:38,000 --> 00:32:41,819
you know, uh share resources and compete with the big players.

695
00:32:41,829 --> 00:32:44,819
Let's say you all built one huge large language model

696
00:32:45,170 --> 00:32:48,099
uh within your group of smaller players and

697
00:32:48,109 --> 00:32:50,500
then everybody benefits from that large language model

698
00:32:50,739 --> 00:32:54,859
and now you can compete with the big players. So that make that's a clear incentive to

699
00:32:54,959 --> 00:32:56,790
share in that group.

700
00:32:57,219 --> 00:33:00,680
Um Now there's also other reasons why people might want to share,

701
00:33:00,689 --> 00:33:03,819
which is like we're all stuck with a problem together, which is,

702
00:33:04,209 --> 00:33:08,859
uh, you know, climate change. Right. So for some strange reason we think that,

703
00:33:09,479 --> 00:33:10,180
um,

704
00:33:10,380 --> 00:33:12,209
we can pollute this earth,

705
00:33:12,319 --> 00:33:17,599
um, and, uh, you know, push carbon into an atmosphere which is a shared resource,

706
00:33:18,030 --> 00:33:18,670
um,

707
00:33:18,859 --> 00:33:19,680
but not

708
00:33:19,939 --> 00:33:22,790
pay the bill basically for doing that. Right.

709
00:33:22,839 --> 00:33:25,869
Um, we, we, we, we somehow think that's ok to do and,

710
00:33:26,140 --> 00:33:27,780
but I think there is a sort of

711
00:33:27,939 --> 00:33:32,099
ethical awareness within a lot of companies,

712
00:33:32,290 --> 00:33:35,209
big companies, big tech companies definitely

713
00:33:35,650 --> 00:33:36,790
who are saying, well, we should,

714
00:33:36,800 --> 00:33:39,989
we should all act together to do something about that, right?

715
00:33:40,000 --> 00:33:42,469
Um So most of these companies have

716
00:33:43,140 --> 00:33:45,239
climate uh sort of

717
00:33:45,739 --> 00:33:46,589
um

718
00:33:46,910 --> 00:33:49,910
promises or what do you call them? Um sustainability,

719
00:33:50,689 --> 00:33:51,040
sustains

720
00:33:51,660 --> 00:33:52,709
and things like this. Um

721
00:33:53,069 --> 00:33:56,829
So to be carbon neutral or negative by 2030

722
00:33:56,939 --> 00:33:59,689
all these kinds of things. So, so they, they're trying, although they're

723
00:33:59,819 --> 00:34:04,119
tied up in an AI arms race and so it's very hard to actually make those goals,

724
00:34:04,130 --> 00:34:05,699
but let's say that they're, you know,

725
00:34:05,849 --> 00:34:06,949
they're trying to do this.

726
00:34:07,109 --> 00:34:10,889
And so there it makes some sense to pool resources, I think and say, OK,

727
00:34:10,899 --> 00:34:14,250
let's be good actors in this world with good citizens and

728
00:34:14,530 --> 00:34:18,840
actually, you know, you know, release some of the data to the public so others can,

729
00:34:18,850 --> 00:34:20,050
you know, help, for instance,

730
00:34:20,648 --> 00:34:20,658
a,

731
00:34:20,759 --> 00:34:25,108
you know, improve the technology to capture the carbon out of the atmosphere.

732
00:34:25,800 --> 00:34:26,330
Hm

733
00:34:27,199 --> 00:34:27,989
The um

734
00:34:29,000 --> 00:34:32,060
I wanted to maybe pivot a little bit um

735
00:34:33,260 --> 00:34:36,639
to, to, to talk about your new company,

736
00:34:36,870 --> 00:34:39,360
but maybe as a way of getting there,

737
00:34:40,340 --> 00:34:42,090
one of the things that I admire about

738
00:34:42,100 --> 00:34:44,639
what you've done and I'm always interested to hear

739
00:34:45,620 --> 00:34:48,478
the different logic is the role of academia,

740
00:34:49,340 --> 00:34:52,918
industry, big industry, like big tech companies and start ups.

741
00:34:54,250 --> 00:34:55,020
What,

742
00:34:55,610 --> 00:34:57,389
what can a university achieve?

743
00:34:58,239 --> 00:35:00,510
What's the advantage of a start up? Essentially?

744
00:35:00,520 --> 00:35:03,510
What, what, what, what drove you to create this new company?

745
00:35:03,520 --> 00:35:04,409
Is there a specific thing?

746
00:35:04,649 --> 00:35:05,030
I, I

747
00:35:05,250 --> 00:35:08,520
can just move faster by doing it as a start up versus

748
00:35:08,709 --> 00:35:11,300
I'm interested to see how you've seen over your career,

749
00:35:11,310 --> 00:35:15,120
the sort of benefits of these three different places.

750
00:35:15,550 --> 00:35:18,530
Yeah, I find it very interesting because there really three modes of operation.

751
00:35:18,540 --> 00:35:22,300
I've tried all of them now so I can sort of sampled them a little bit.

752
00:35:22,870 --> 00:35:23,399
Um

753
00:35:24,979 --> 00:35:27,620
Now universities have a very special role of educating

754
00:35:27,629 --> 00:35:30,310
the next generation of talent that's really important and,

755
00:35:30,320 --> 00:35:31,959
you know, they use taxpayer money for that.

756
00:35:31,969 --> 00:35:33,860
So, you know, that's incredibly important,

757
00:35:34,129 --> 00:35:35,469
but they also do

758
00:35:35,760 --> 00:35:36,310
um

759
00:35:36,419 --> 00:35:40,790
so much more exploratory research, right? So they, they can, you know, uh

760
00:35:40,969 --> 00:35:45,350
if you like to think about the inside of a black hole, you know, fine, do it in a,

761
00:35:45,360 --> 00:35:46,679
in a university setting.

762
00:35:46,689 --> 00:35:48,149
There's no company that will, well,

763
00:35:48,159 --> 00:35:50,360
there's very few companies that will fund that in some sense,

764
00:35:50,770 --> 00:35:52,719
basically. No, I think at this point.

765
00:35:53,800 --> 00:35:54,300
Um

766
00:35:54,780 --> 00:35:55,770
So, um

767
00:35:56,439 --> 00:35:59,820
but the impact is very diffuse. Right. So you, you, you write a paper,

768
00:36:00,270 --> 00:36:00,500
um,

769
00:36:00,510 --> 00:36:04,060
and that paper gets picked up maybe by different groups

770
00:36:04,070 --> 00:36:06,500
and they build on it and that's a very indirect,

771
00:36:06,540 --> 00:36:09,739
uh but important way to make impact and, you know, it's also,

772
00:36:10,189 --> 00:36:14,219
you know, of course, you, you, uh, it's also a different style of doing research and,

773
00:36:14,229 --> 00:36:16,780
and, and being engaged in intellectual activity.

774
00:36:17,500 --> 00:36:20,510
Um now the big companies and the start ups,

775
00:36:20,770 --> 00:36:22,320
you know, they can um

776
00:36:22,760 --> 00:36:28,399
command much bigger resources to really go after a specific target, right? So, um

777
00:36:29,429 --> 00:36:32,610
no, but they are commercial, right? So they are tied to commercial goals.

778
00:36:32,620 --> 00:36:34,419
And so you have to really align

779
00:36:34,800 --> 00:36:38,610
the commercial goal with the thing that you want to achieve.

780
00:36:39,389 --> 00:36:40,090
Um

781
00:36:40,639 --> 00:36:44,429
Now some people like, you know, if you, if you like to achieve AGI, you know, great.

782
00:36:44,439 --> 00:36:46,610
So you can work for one of these big companies.

783
00:36:46,620 --> 00:36:50,110
Um that's a perfect alignment because that's what these big companies want. Do.

784
00:36:50,120 --> 00:36:52,129
They think they can make big money on that.

785
00:36:52,139 --> 00:36:54,129
So, you know, that's where you can sort of do that,

786
00:36:55,020 --> 00:37:00,260
that research and, and you can use the actual resources like massive amounts of GPUs

787
00:37:00,780 --> 00:37:01,959
um to achieve that.

788
00:37:03,129 --> 00:37:06,550
But big companies are also in a way slow and political

789
00:37:07,000 --> 00:37:10,350
beasts, right? There's like, uh there's a lot of people that need to,

790
00:37:10,939 --> 00:37:13,550
uh you know, agree on something and, you know,

791
00:37:13,750 --> 00:37:13,760
a

792
00:37:13,879 --> 00:37:17,659
lot of legal involvement if you wanna change something small.

793
00:37:17,669 --> 00:37:21,590
And so it's, it's, it's, it's very uh fisc this whole thing

794
00:37:21,709 --> 00:37:23,479
talking about fluid.

795
00:37:23,780 --> 00:37:25,290
You know, it's like it's very fisc

796
00:37:25,429 --> 00:37:26,429
thing. So, um

797
00:37:27,270 --> 00:37:27,899
and

798
00:37:28,070 --> 00:37:28,080
a

799
00:37:28,889 --> 00:37:33,379
and a start, the great advantage of a start up is that um you're your own boss.

800
00:37:33,389 --> 00:37:34,909
So if you have a vision,

801
00:37:34,919 --> 00:37:38,179
you can execute on your own vision and you don't have to constantly

802
00:37:38,489 --> 00:37:41,310
calibrate with other people higher up in your organization,

803
00:37:41,320 --> 00:37:44,129
you just need a great set of co-founders and

804
00:37:44,260 --> 00:37:46,010
a great team to execute

805
00:37:46,159 --> 00:37:48,949
who are aligned with that vision. And then you can really go.

806
00:37:49,479 --> 00:37:52,929
Um So to my surprise, um perhaps is that

807
00:37:53,600 --> 00:37:54,100
um

808
00:37:54,469 --> 00:37:59,810
the amount of resources you can get in a start up these days in the field of AI is

809
00:38:00,179 --> 00:38:02,219
no less than what you would get

810
00:38:02,489 --> 00:38:03,620
in a big tech company.

811
00:38:03,870 --> 00:38:04,500
So,

812
00:38:05,219 --> 00:38:09,580
in fact, um you know, if you can tap into VC capital,

813
00:38:10,030 --> 00:38:14,300
um I've had until now, incredibly positive experiences with this,

814
00:38:14,310 --> 00:38:16,060
which means that uh first of all,

815
00:38:16,790 --> 00:38:19,729
you know, these are very smart people, you know, of course, they, you know,

816
00:38:19,739 --> 00:38:22,070
they want, of course get return on investment.

817
00:38:22,080 --> 00:38:24,489
So there's no idealism here mostly.

818
00:38:25,209 --> 00:38:29,239
Um but they're very smart people, they help you find a market, they help you

819
00:38:29,590 --> 00:38:30,639
build a

820
00:38:30,760 --> 00:38:31,830
healthy business.

821
00:38:33,560 --> 00:38:34,149
Um

822
00:38:34,340 --> 00:38:37,500
And uh and there's lots of money available as well, right,

823
00:38:37,510 --> 00:38:39,939
for that particular purpose that you want to pursue.

824
00:38:39,949 --> 00:38:40,479
Um

825
00:38:40,850 --> 00:38:41,649
And so,

826
00:38:41,949 --> 00:38:42,739
and so I think

827
00:38:43,419 --> 00:38:44,669
the agility

828
00:38:45,469 --> 00:38:48,250
and also the positive attitude

829
00:38:48,770 --> 00:38:53,449
that you find in start up land I really like. So I, I guess I've now

830
00:38:54,250 --> 00:38:56,790
converged on that particular model and I'll, I'll,

831
00:38:56,800 --> 00:38:58,610
I'll stick with that now for a while

832
00:38:59,310 --> 00:39:02,360
and, and just before we get into the Pacifics um

833
00:39:02,860 --> 00:39:05,340
of, of your company, is there any

834
00:39:06,070 --> 00:39:10,290
differences or challenges between, let's say, in your experience,

835
00:39:10,659 --> 00:39:12,260
us, Bay area,

836
00:39:13,000 --> 00:39:15,179
Europe, you know, other

837
00:39:15,429 --> 00:39:19,889
advantages, disadvantages in terms of finding the staff, finding the,

838
00:39:20,510 --> 00:39:21,379
the the money.

839
00:39:22,310 --> 00:39:27,899
Well, we actually do use uh American and somewhat and English VCs,

840
00:39:27,909 --> 00:39:29,669
mostly there's also a few

841
00:39:29,860 --> 00:39:33,679
continental Europe, Dutch investors, but mostly it's

842
00:39:33,780 --> 00:39:33,840
uh

843
00:39:34,139 --> 00:39:35,729
we tapping into uh

844
00:39:36,409 --> 00:39:40,600
you know, um UK and US based VC firms,

845
00:39:41,040 --> 00:39:46,050
although our lead investor is actually is a UK based investor

846
00:39:47,110 --> 00:39:47,500
A me.

847
00:39:48,270 --> 00:39:48,919
So

848
00:39:50,080 --> 00:39:53,500
um so I don't think you need to make that distinction in some sense.

849
00:39:53,760 --> 00:39:58,459
The nice thing is that these big investors, they're turning their side to Europe.

850
00:39:58,770 --> 00:39:59,979
And the reason is that

851
00:40:00,149 --> 00:40:02,620
there's just incredible talent pool in Europe.

852
00:40:03,129 --> 00:40:03,729
Many of

853
00:40:03,949 --> 00:40:08,020
many of these talent pool likes to stay in Europe because Europe is just great, just,

854
00:40:08,030 --> 00:40:09,459
just fun place to be

855
00:40:10,919 --> 00:40:17,060
and the salaries are a lot lower than in Bay Area.

856
00:40:18,090 --> 00:40:19,909
Um And so with relatively

857
00:40:20,590 --> 00:40:22,969
little investment, well,

858
00:40:22,979 --> 00:40:25,959
less investment than what you would have to invest in Bay Area,

859
00:40:25,969 --> 00:40:27,909
you can get a excellent team.

860
00:40:28,699 --> 00:40:32,969
Um And so it only makes a lot of sense that also these investors turn their eyes on,

861
00:40:32,979 --> 00:40:33,639
on Europe.

862
00:40:33,649 --> 00:40:33,969
So

863
00:40:34,330 --> 00:40:38,810
I think we will see a lot of growth and activity in these, in these sort of uh

864
00:40:38,989 --> 00:40:42,250
start up and scale ups in, in Europe in the coming years.

865
00:40:43,500 --> 00:40:44,649
I've often um

866
00:40:44,800 --> 00:40:47,129
I tease some of my American colleagues that

867
00:40:47,879 --> 00:40:49,840
why are they all based in Seattle?

868
00:40:49,850 --> 00:40:53,669
It seems like the most crazy time zone and position in the world to have such a,

869
00:40:53,679 --> 00:40:56,199
if you were going to invent a company to have a global reach,

870
00:40:56,209 --> 00:40:57,800
surely you wouldn't put it

871
00:40:58,070 --> 00:41:00,370
there. I still don't understand how this,

872
00:41:01,129 --> 00:41:04,100
but yeah, something to do with ecosystems, right? So, um

873
00:41:05,000 --> 00:41:09,739
so, and, and that's really the thing. So uh if you build a particular

874
00:41:10,419 --> 00:41:11,889
nucleus or particular

875
00:41:12,129 --> 00:41:16,000
geographic area where, where it's lots of things are happening, right?

876
00:41:16,010 --> 00:41:19,629
In Silicon Valley, you have the big universities like Berkeley and Stanford,

877
00:41:20,169 --> 00:41:21,020
um

878
00:41:21,310 --> 00:41:24,840
which are providing a lot of talent and there is a lot of

879
00:41:25,360 --> 00:41:29,679
entrepreneurial spirit in those places and there's a whole,

880
00:41:29,689 --> 00:41:33,629
it think of it as a supply line sort of issue where there's a lot of,

881
00:41:34,560 --> 00:41:36,540
you know, other things which work for them.

882
00:41:36,550 --> 00:41:39,679
So there's a very small, you know, everybody knows each other in the VC.

883
00:41:39,689 --> 00:41:42,620
So there's very, there's a lot of VCs which can fund these things and,

884
00:41:42,879 --> 00:41:43,159
you know,

885
00:41:43,669 --> 00:41:45,590
so I think it has to do with the fact

886
00:41:45,600 --> 00:41:49,169
that once you build a really good ecosystem locally,

887
00:41:49,560 --> 00:41:53,739
it then becomes very attractive to be there to do your start up

888
00:41:54,120 --> 00:41:57,100
because it's very easy to get good ideas from, you know,

889
00:41:57,110 --> 00:41:59,729
people help each other to grow these start ups.

890
00:41:59,739 --> 00:41:59,790
It's

891
00:41:59,929 --> 00:42:01,919
very collaborative atmosphere,

892
00:42:02,149 --> 00:42:02,860
it's easy.

893
00:42:02,870 --> 00:42:04,469
You know, if I need a new investment,

894
00:42:04,479 --> 00:42:07,600
I talk to a few people and they point me to other people and then you, you know,

895
00:42:07,610 --> 00:42:09,899
you before you know it, you're in front of new investors.

896
00:42:09,909 --> 00:42:10,219
So

897
00:42:10,340 --> 00:42:12,370
I think that kind of uh

898
00:42:13,050 --> 00:42:14,620
you know, lubricant

899
00:42:14,760 --> 00:42:17,840
in some sense is really good in, in these ecosystems.

900
00:42:17,850 --> 00:42:20,889
So what we need to do in Europe is to build these ecosystems.

901
00:42:21,110 --> 00:42:23,419
And I think in Cambridge and in London,

902
00:42:23,600 --> 00:42:26,699
these ecosystems exist so they are very good as well.

903
00:42:26,939 --> 00:42:28,959
Um Amsterdam, Berlin,

904
00:42:29,360 --> 00:42:32,810
you know, some other places, Paris for sure. Um

905
00:42:32,919 --> 00:42:34,199
maybe Stockholm.

906
00:42:34,320 --> 00:42:38,530
So some of these places in Europe also start to develop these ecosystems,

907
00:42:38,540 --> 00:42:40,949
but we need to get better at that in Europe.

908
00:42:42,580 --> 00:42:45,919
Yeah, I I do definitely agree that there seems to be a lot of um

909
00:42:47,330 --> 00:42:52,669
a lot of very talented researchers and engineers and scientists in Europe that

910
00:42:52,939 --> 00:42:55,149
maybe feel a pressure to perhaps to move

911
00:42:55,580 --> 00:42:56,860
to, to the US

912
00:42:56,969 --> 00:43:00,510
where probably a lot of them would probably rather stay in Europe if they could do.

913
00:43:00,800 --> 00:43:04,909
So. There is that I agree there seems to be a desire and if you could tap into that,

914
00:43:05,040 --> 00:43:05,909
you've got a big

915
00:43:06,399 --> 00:43:09,860
uh pool as and the other benefits of time zones

916
00:43:10,090 --> 00:43:10,620
and

917
00:43:10,800 --> 00:43:12,520
access to, to different markets.

918
00:43:12,530 --> 00:43:16,510
But yeah, I'd, I'd love to learn more a little bit um about your company.

919
00:43:16,520 --> 00:43:17,780
And, and maybe also,

920
00:43:18,219 --> 00:43:21,620
I think listeners to this podcast may be a little bit more familiar with

921
00:43:21,760 --> 00:43:24,419
uh some of the topics we discussed around fluid dynamics.

922
00:43:24,429 --> 00:43:26,689
So it would also be good perhaps for you to

923
00:43:27,419 --> 00:43:28,790
align how some,

924
00:43:28,800 --> 00:43:33,090
maybe the material discovery and material science has some overlaps and maybe

925
00:43:33,340 --> 00:43:35,149
uh differences to

926
00:43:35,459 --> 00:43:35,840
tonics.

927
00:43:36,479 --> 00:43:39,010
So the start up is about material discovery

928
00:43:39,229 --> 00:43:40,739
um for carbon capture.

929
00:43:40,860 --> 00:43:42,679
Um And so we focus on

930
00:43:43,159 --> 00:43:48,020
uh uh um a sort of a family of molecules called uh metal–organic frameworks.

931
00:43:48,669 --> 00:43:51,010
Um These consist of uh sort of,

932
00:43:51,020 --> 00:43:54,479
you can think of them as a sort of a lattice structure with, on the nodes,

933
00:43:54,489 --> 00:43:55,610
you typically put

934
00:43:55,899 --> 00:43:57,729
some kind of uh you know,

935
00:43:59,070 --> 00:44:03,110
you know, small little molecule piece with a metal in it.

936
00:44:03,120 --> 00:44:06,370
Um And then they get connected by organic linkers is what they called.

937
00:44:07,560 --> 00:44:09,979
Um And so there's a huge design space,

938
00:44:09,989 --> 00:44:14,379
like many trillions of possible things that you can sort of even, you know, imagine

939
00:44:14,840 --> 00:44:16,659
uh with very different properties.

940
00:44:17,250 --> 00:44:18,439
And these um

941
00:44:18,679 --> 00:44:20,290
these frameworks uh

942
00:44:20,770 --> 00:44:22,629
if you blow, let's say

943
00:44:23,050 --> 00:44:24,110
air through them,

944
00:44:24,979 --> 00:44:28,149
they tend to bind the molecules in the air

945
00:44:28,600 --> 00:44:30,639
uh to the to the framework.

946
00:44:30,649 --> 00:44:35,739
So for instance, carbon dioxide binds but hydrogen uh water,

947
00:44:36,080 --> 00:44:39,429
um sorry, I say water also binds nitrogen, binds.

948
00:44:39,439 --> 00:44:42,800
So all of these molecules bind to them and you want to find

949
00:44:43,250 --> 00:44:49,000
the uh metal organic framework that preferentially binds carbon dioxide

950
00:44:49,459 --> 00:44:53,399
um relative to water and nitrogen and all these other molecules.

951
00:44:53,790 --> 00:44:56,610
And then you want to do this at a particular temperature and pressure.

952
00:44:57,229 --> 00:44:59,689
Um And then you change the temperature and pressure.

953
00:45:00,179 --> 00:45:01,409
Um let's say you, you

954
00:45:02,360 --> 00:45:04,879
have less pressure and higher temperature

955
00:45:05,040 --> 00:45:07,949
that would sort of release then the carbon again and then you can sort

956
00:45:07,959 --> 00:45:11,500
of sequester it and sort of put it away or reuse it for something.

957
00:45:12,219 --> 00:45:14,489
Um So, so that's the basic

958
00:45:14,659 --> 00:45:19,479
idea. And now we are going to use machine learning to accelerate the process a lot.

959
00:45:20,469 --> 00:45:20,750
All right.

960
00:45:20,760 --> 00:45:21,159
So we're gonna,

961
00:45:21,169 --> 00:45:23,909
we're gonna use the same generative models that are

962
00:45:23,919 --> 00:45:26,949
being used to generate images to generate new materials.

963
00:45:27,600 --> 00:45:28,679
Um And then we're gonna

964
00:45:29,399 --> 00:45:32,959
test those materials in a chemistry pipeline, but those,

965
00:45:33,350 --> 00:45:35,219
those are also

966
00:45:35,379 --> 00:45:35,899
um

967
00:45:36,550 --> 00:45:40,850
infused with machine learning methods to speed up this, this testing framework

968
00:45:41,179 --> 00:45:44,120
of how good this particular proposed material is.

969
00:45:44,500 --> 00:45:47,580
And then we have a search agent that tries to, you know,

970
00:45:47,719 --> 00:45:50,080
orchestrate this, this, this,

971
00:45:50,409 --> 00:45:50,729
you know,

972
00:45:50,739 --> 00:45:53,050
searching through the space of molecules to find the

973
00:45:53,060 --> 00:45:56,169
best molecule with certain properties as quickly as possible.

974
00:45:57,280 --> 00:46:00,459
Um And you can, so how does this connect to fluids? Um Well, you a

975
00:46:00,689 --> 00:46:02,409
gas is not quite a fluid.

976
00:46:02,419 --> 00:46:07,060
Um but you can, you know, you could imagine actually a fluid in a,

977
00:46:07,070 --> 00:46:08,479
in a mo that's actually what happens.

978
00:46:08,489 --> 00:46:09,479
So you can sort of uh

979
00:46:09,909 --> 00:46:12,070
you can also put fluids in MOFs.

980
00:46:12,580 --> 00:46:13,129
Um

981
00:46:13,320 --> 00:46:15,449
But let's imagine a gas where you can sort of

982
00:46:15,459 --> 00:46:18,770
describe a gas but somewhat similar equations as a fluid.

983
00:46:19,439 --> 00:46:21,060
Um And, you know,

984
00:46:21,429 --> 00:46:22,419
there's sort of

985
00:46:23,080 --> 00:46:23,090
a,

986
00:46:23,219 --> 00:46:23,229
a,

987
00:46:23,629 --> 00:46:24,110
you know,

988
00:46:24,120 --> 00:46:28,989
an equation that describes how this gas would blow through this particular um

989
00:46:29,139 --> 00:46:34,010
framework and then, you know, and how it binds the molecules to the framework.

990
00:46:34,020 --> 00:46:36,739
So that, that is not very unlike how you would

991
00:46:37,320 --> 00:46:41,010
uh simulate a fluid maybe um in, in some,

992
00:46:41,300 --> 00:46:42,229
you know, in some

993
00:46:42,350 --> 00:46:44,540
space with certain boundaries or something.

994
00:46:45,560 --> 00:46:47,939
And, and how do people do it now,

995
00:46:48,229 --> 00:46:50,179
you know, because there are companies

996
00:46:50,389 --> 00:46:54,600
trying to do these kind of, so are they relying on more traditional physics based

997
00:46:54,949 --> 00:46:56,280
simulations

998
00:46:56,669 --> 00:46:57,899
to do these discoveries?

999
00:46:58,270 --> 00:47:00,020
Yeah. So um there is already

1000
00:47:00,250 --> 00:47:01,659
people who are um

1001
00:47:02,370 --> 00:47:06,169
having these kind of pipelines. So uh they are mostly chemists.

1002
00:47:06,179 --> 00:47:09,270
So it's, it's a chemistry pipeline or workflow

1003
00:47:09,629 --> 00:47:13,689
um where um you know, there's a database of um

1004
00:47:14,000 --> 00:47:14,830
you know, known

1005
00:47:15,489 --> 00:47:20,969
um metal–organic frameworks and you push them through a chem chemistry

1006
00:47:21,270 --> 00:47:23,770
simulation pipeline that sort of simulates all the

1007
00:47:23,780 --> 00:47:26,340
molecules as they wiggle around in this particular

1008
00:47:26,689 --> 00:47:30,909
uh environment. And then you can sort of measure how many of them would

1009
00:47:31,260 --> 00:47:33,590
would bind at certain temperatures and pressures.

1010
00:47:34,070 --> 00:47:36,020
Um And that's, and that

1011
00:47:36,270 --> 00:47:38,739
turns into a number that says how good this thing is.

1012
00:47:38,750 --> 00:47:40,250
And then, you know, you have some,

1013
00:47:40,530 --> 00:47:43,870
some sim simple way of searching through the space. Now, you can see that

1014
00:47:44,850 --> 00:47:47,919
that can be massively improved with machine learning techniques.

1015
00:47:47,929 --> 00:47:50,350
That's why we think it's, it's such an exciting field

1016
00:47:50,810 --> 00:47:54,530
because they are not generating new materials with diffusion models.

1017
00:47:54,820 --> 00:47:58,270
Um They don't use very sophisticated search algorithms either.

1018
00:47:58,860 --> 00:48:00,550
Um in order to um

1019
00:48:01,929 --> 00:48:04,939
you know, to do, only do the simulations for the ones that are

1020
00:48:05,110 --> 00:48:05,949
important.

1021
00:48:06,449 --> 00:48:07,469
Um And

1022
00:48:08,669 --> 00:48:12,379
you can even accelerate the simulation models by, you know,

1023
00:48:12,679 --> 00:48:15,810
predicting the properties directly using machine learning models.

1024
00:48:16,459 --> 00:48:18,520
Um or by

1025
00:48:18,750 --> 00:48:19,449
what's called

1026
00:48:19,639 --> 00:48:22,580
training force fields, these are methods that

1027
00:48:23,300 --> 00:48:26,159
compute the forces on atoms as they wiggle.

1028
00:48:26,850 --> 00:48:30,270
Typically, you have to do this with quantum mechanics, it's very expensive.

1029
00:48:30,280 --> 00:48:33,169
Um but you could do it with a machine learned force field

1030
00:48:33,510 --> 00:48:38,070
which is again way, way faster, many orders of magnitude faster than a normal

1031
00:48:38,510 --> 00:48:42,310
uh force field. Uh if you use quantum mechanical calculations.

1032
00:48:42,629 --> 00:48:45,949
Um but almost as accurate as that quantum mechanical calculation.

1033
00:48:47,399 --> 00:48:50,689
OK. Interesting. And what made you target this

1034
00:48:51,580 --> 00:48:52,399
area?

1035
00:48:52,610 --> 00:48:55,949
Is it more as the climate change sustainability?

1036
00:48:55,959 --> 00:48:59,939
And is that a sort of a personal thing of yours that you've wanted to do?

1037
00:48:59,949 --> 00:49:00,719
Cos I know you've

1038
00:49:00,860 --> 00:49:03,219
had a focus in many areas of science.

1039
00:49:03,229 --> 00:49:06,760
You know, I'm just wondering what made you focus on this area in particular.

1040
00:49:07,830 --> 00:49:11,010
Yeah, it's definitely uh a personal uh

1041
00:49:11,159 --> 00:49:13,709
sort of preference for me and my

1042
00:49:13,929 --> 00:49:15,679
co-founder Chad Edwards

1043
00:49:16,409 --> 00:49:16,790
a me.

1044
00:49:17,780 --> 00:49:20,340
But also we think there is a big market for this

1045
00:49:20,489 --> 00:49:21,520
because I think,

1046
00:49:22,260 --> 00:49:24,189
you know, companies do want to

1047
00:49:24,669 --> 00:49:28,139
be a good citizen and, you know, compensate their carbon emissions.

1048
00:49:28,149 --> 00:49:31,679
And at some point, it might actually be enforced by government, which is what I hope,

1049
00:49:31,689 --> 00:49:33,760
you know, we need to tax pollution.

1050
00:49:34,699 --> 00:49:36,030
Um And then having

1051
00:49:36,199 --> 00:49:38,520
um a solution available

1052
00:49:39,010 --> 00:49:40,040
to actually

1053
00:49:40,300 --> 00:49:44,040
capture that carbon is, is there going to be a big market, I think as well?

1054
00:49:44,050 --> 00:49:46,479
So it's, it's it's an alignment again between

1055
00:49:46,719 --> 00:49:49,199
something you really want to do and work on with

1056
00:49:49,739 --> 00:49:50,810
a commercial

1057
00:49:50,939 --> 00:49:54,070
angle because otherwise you cannot build that company,

1058
00:49:54,260 --> 00:49:54,479
that

1059
00:49:54,610 --> 00:49:57,090
a healthy company that would actually make that impact.

1060
00:49:57,100 --> 00:49:58,350
So that's the way I view that.

1061
00:49:59,479 --> 00:50:02,030
Um But having said that, you know,

1062
00:50:02,040 --> 00:50:06,090
there is many other directions in which this platform could be pointed

1063
00:50:06,770 --> 00:50:10,870
even for metal–organic frameworks, um you can store hydrogen,

1064
00:50:11,280 --> 00:50:13,709
you can catalyze, you can um

1065
00:50:14,729 --> 00:50:20,590
um you can sort of deliver drugs, uh you can detect toxins, uh you can

1066
00:50:20,919 --> 00:50:24,149
clean water and that's only metal–organic frameworks, right?

1067
00:50:24,159 --> 00:50:25,979
But then we can also go to other markets

1068
00:50:25,989 --> 00:50:28,580
at some point um that are completely different materials.

1069
00:50:29,290 --> 00:50:30,770
And how does it feel?

1070
00:50:30,780 --> 00:50:36,040
I think you alluded to um what many people who work for large companies feel, which is

1071
00:50:36,219 --> 00:50:38,669
the benefits of working for large companies, the, you know,

1072
00:50:38,679 --> 00:50:41,020
access to a great talent pool, but maybe the

1073
00:50:41,419 --> 00:50:46,000
slight slowing down and sort of meetings to decide other meetings.

1074
00:50:46,239 --> 00:50:48,310
Have you felt a certain sort of

1075
00:50:48,780 --> 00:50:53,030
energy of being uh back in a, in a start up again.

1076
00:50:53,399 --> 00:50:54,260
Definitely,

1077
00:50:54,850 --> 00:50:58,189
I've definitely felt a lot of energy being back in a start up.

1078
00:50:58,659 --> 00:51:01,409
It is, uh I think it is no comparison

1079
00:51:01,959 --> 00:51:03,959
in terms of, uh you know, the,

1080
00:51:04,419 --> 00:51:04,919
I don't know

1081
00:51:05,300 --> 00:51:06,719
the way in which,

1082
00:51:07,120 --> 00:51:10,800
you know, you can motivate people to all work on this problem.

1083
00:51:10,810 --> 00:51:14,959
And um and it's, it's, it's somewhat small group at this point. Of course,

1084
00:51:15,229 --> 00:51:17,810
when these companies grow much bigger, there's also, of course, you know,

1085
00:51:17,820 --> 00:51:20,739
how do you maintain that spirit is not so easy, but,

1086
00:51:21,100 --> 00:51:24,760
you know, as a start up, that's very special because you're small, um,

1087
00:51:24,770 --> 00:51:28,649
you want to change the world, you have that vision to do that and you have,

1088
00:51:29,280 --> 00:51:34,899
you know, you can do it quick and fast with a lot of money actually under your wings.

1089
00:51:35,610 --> 00:51:38,870
So it's a big responsibility on the one hand, on the other hand,

1090
00:51:38,879 --> 00:51:41,030
it's also an incredible opportunity.

1091
00:51:41,040 --> 00:51:41,689
And,

1092
00:51:41,939 --> 00:51:42,709
yeah, and,

1093
00:51:42,850 --> 00:51:46,360
and really a little bit of a different feel than working in a big company.

1094
00:51:47,050 --> 00:51:47,570
Yeah,

1095
00:51:47,979 --> 00:51:49,540
I wanted to

1096
00:51:49,790 --> 00:51:51,770
pivot a little bit to

1097
00:51:52,709 --> 00:51:54,389
get your advice really.

1098
00:51:54,399 --> 00:51:59,100
And some of your, uh uh, yeah, maybe your advice, I guess to, to people who are

1099
00:51:59,459 --> 00:52:02,370
early on in their careers, I think you've

1100
00:52:02,729 --> 00:52:06,770
had a very interesting trajectory and, and, and kind of movement if you,

1101
00:52:07,689 --> 00:52:08,739
what would you recommend?

1102
00:52:08,750 --> 00:52:11,620
So if you're, you're going back, you're doing your undergraduate degree.

1103
00:52:12,449 --> 00:52:14,750
Let's say you've already decided to do a PhD.

1104
00:52:16,379 --> 00:52:17,830
Would you recommend

1105
00:52:18,260 --> 00:52:22,360
go do a postdoc, try and go the academic route? Would you suggest to go to a start up?

1106
00:52:22,820 --> 00:52:27,429
How do you navigate this for people who wanted to sort of follow in your footsteps?

1107
00:52:27,439 --> 00:52:30,510
What was, is there anything that you would do again or do differently?

1108
00:52:31,560 --> 00:52:35,969
So, I should say I did many, many postdocs, right. So, um

1109
00:52:36,120 --> 00:52:42,610
I did, uh I, I graduated in 98 and then I did a couple of years at Caltech and then I did

1110
00:52:42,840 --> 00:52:46,149
and another three years with Geoffrey Hinton and do two different places

1111
00:52:46,500 --> 00:52:47,939
and I just loved it.

1112
00:52:48,090 --> 00:52:48,659
So,

1113
00:52:49,100 --> 00:52:51,949
so the first thing I want to say, it depends a lot on who you are.

1114
00:52:52,879 --> 00:52:54,649
Um And also, um

1115
00:52:55,469 --> 00:52:58,810
so that really suited me at that stage in my life.

1116
00:52:58,820 --> 00:53:01,449
It was incredibly interested in fundamental

1117
00:53:01,679 --> 00:53:03,320
science and um

1118
00:53:03,530 --> 00:53:06,040
I didn't get paid a lot at all.

1119
00:53:06,050 --> 00:53:09,330
Um But I didn't care at all, you know, it's just, it was a beautiful life,

1120
00:53:09,629 --> 00:53:12,949
you know, uh having very little money to spend and just being,

1121
00:53:13,060 --> 00:53:13,679
you know,

1122
00:53:13,939 --> 00:53:15,250
being a scientist.

1123
00:53:16,100 --> 00:53:19,719
Um So these days, but, but, but I didn't have that choice, right?

1124
00:53:19,729 --> 00:53:23,330
So that was actually different and interesting. So these days

1125
00:53:24,040 --> 00:53:26,969
it's much harder for young people because they see,

1126
00:53:27,300 --> 00:53:29,620
you know, this other opportunity, clear

1127
00:53:29,850 --> 00:53:31,290
clearly in front of them, right?

1128
00:53:31,300 --> 00:53:33,379
And they say I could, I do that, you know,

1129
00:53:33,389 --> 00:53:36,320
and earn like 10 times as much as I can earn there.

1130
00:53:36,709 --> 00:53:36,820
Is

1131
00:53:37,090 --> 00:53:40,340
it worth, is it worth for me to just go to this

1132
00:53:40,530 --> 00:53:42,060
do this academic route? And

1133
00:53:42,750 --> 00:53:44,179
you know, honestly academics

1134
00:53:44,560 --> 00:53:47,850
working in academia is also not all positive, right?

1135
00:53:47,860 --> 00:53:50,570
At some point, you, you know, you're asked to juggle

1136
00:53:50,939 --> 00:53:52,889
many balls, like you have to

1137
00:53:53,199 --> 00:53:55,879
write grants, you have to teach, you have to basically,

1138
00:53:56,570 --> 00:54:00,020
you know, run your own business. You have to be good people, a good manager.

1139
00:54:00,030 --> 00:54:01,389
You know, you have to be good at research.

1140
00:54:01,399 --> 00:54:03,679
You have to be good at everything basically. And then you,

1141
00:54:04,070 --> 00:54:06,879
you don't have job security until you get tenure.

1142
00:54:07,090 --> 00:54:10,429
It's really in that sense, a pretty lousy deal if you think about it.

1143
00:54:10,439 --> 00:54:12,070
So you have, you have to really,

1144
00:54:13,320 --> 00:54:13,830
you know,

1145
00:54:14,310 --> 00:54:19,169
want, you want, you, you should be an educator. So the good thing about academia is

1146
00:54:20,379 --> 00:54:22,399
it's great to work with young people,

1147
00:54:22,689 --> 00:54:25,550
right? It's fantastic to help people grow

1148
00:54:26,060 --> 00:54:28,330
and I still sometimes get emails from people.

1149
00:54:28,449 --> 00:54:31,320
I was in your master class then and then,

1150
00:54:31,330 --> 00:54:36,159
and it's because of you that I took this route and I now have this fantastic job,

1151
00:54:36,260 --> 00:54:36,689
right?

1152
00:54:37,080 --> 00:54:37,820
That is,

1153
00:54:38,000 --> 00:54:39,330
you know, unbelievably

1154
00:54:39,469 --> 00:54:40,860
rewarding to get that.

1155
00:54:41,000 --> 00:54:44,520
Um And that's what you have in academia, you can help people grow,

1156
00:54:44,530 --> 00:54:46,860
you can turn them into great researchers

1157
00:54:46,979 --> 00:54:50,739
and you can see them have stellar careers, which is very rewarding. I think

1158
00:54:52,389 --> 00:54:52,840
so.

1159
00:54:52,850 --> 00:54:56,899
So, so, you know, is that if that's you, you want to work on the inside of a black hole,

1160
00:54:56,909 --> 00:54:59,300
you know what's going on on the inside of a black hole.

1161
00:54:59,570 --> 00:55:01,639
And you like to work with young people

1162
00:55:01,830 --> 00:55:05,399
and you can put up with some annoying nuisances in, in academia.

1163
00:55:05,409 --> 00:55:09,050
Then academia is your, is your thing, I honestly believe and you should,

1164
00:55:09,179 --> 00:55:10,229
and especially,

1165
00:55:10,469 --> 00:55:10,899
um,

1166
00:55:11,689 --> 00:55:14,870
you should not worry about money. It's easy for me to say now.

1167
00:55:14,879 --> 00:55:18,010
Um, but I didn't do it then I didn't worry about it.

1168
00:55:18,020 --> 00:55:20,280
But it was the best thing I decided because

1169
00:55:20,629 --> 00:55:23,669
I could really focus on, you know, building a,

1170
00:55:24,530 --> 00:55:27,590
um, a good foundation for science learning.

1171
00:55:27,600 --> 00:55:31,270
A lot about a lot about different topics and, and,

1172
00:55:31,280 --> 00:55:34,350
and having a sort of a research strategy for myself.

1173
00:55:34,360 --> 00:55:34,969
So I think

1174
00:55:35,149 --> 00:55:36,429
having a postdoc

1175
00:55:36,570 --> 00:55:40,600
on the Ariel Rings is, is really fantastic. And I don't think if you're good postdoc

1176
00:55:40,899 --> 00:55:41,669
and you publish

1177
00:55:42,050 --> 00:55:43,060
well, you know,

1178
00:55:43,889 --> 00:55:47,620
it, it's not a disadvantage either. I would say at, at all,

1179
00:55:47,800 --> 00:55:49,070
but you can also do something else.

1180
00:55:49,080 --> 00:55:52,810
You can also first work for a start up or work first work for, you know,

1181
00:55:53,260 --> 00:55:56,840
for company and then go back to academia. You should, you should feel free to,

1182
00:55:57,169 --> 00:55:58,810
you know, you're not closing any doors.

1183
00:55:58,820 --> 00:55:59,510
I feel, you know,

1184
00:55:59,520 --> 00:56:01,820
going back and forth between East East may maybe

1185
00:56:01,830 --> 00:56:04,429
make sure you publish it now and then something exciting

1186
00:56:04,699 --> 00:56:06,340
if you want to go back to academia.

1187
00:56:07,679 --> 00:56:09,479
But do you think there should be more

1188
00:56:09,879 --> 00:56:11,830
that the complaint I hear,

1189
00:56:12,010 --> 00:56:13,540
uh, or the issue is that

1190
00:56:15,219 --> 00:56:16,300
post doc,

1191
00:56:17,610 --> 00:56:20,389
the funding model, the contract model

1192
00:56:21,260 --> 00:56:25,159
is such that, as you said, for a certain time period,

1193
00:56:25,489 --> 00:56:27,169
you can sort of deal with it and I know from

1194
00:56:27,179 --> 00:56:30,080
my own experiences but there comes a point where you,

1195
00:56:30,090 --> 00:56:30,719
you're sort of,

1196
00:56:31,530 --> 00:56:33,260
you want to buy a house or you want,

1197
00:56:33,560 --> 00:56:35,810
you want to get married or something? There comes a point.

1198
00:56:35,820 --> 00:56:38,030
Do you think universities should do more?

1199
00:56:39,679 --> 00:56:44,129
Oh. Is there any way that you can do more to sort of keep those researchers

1200
00:56:44,699 --> 00:56:45,560
who are great?

1201
00:56:45,570 --> 00:56:47,719
But give them more security or,

1202
00:56:47,729 --> 00:56:51,060
or does that break just the model of how universities work?

1203
00:56:51,939 --> 00:56:52,719
Yeah. I don't know.

1204
00:56:52,830 --> 00:56:54,469
It's a very hard one.

1205
00:56:56,520 --> 00:57:00,070
Yeah. So, in Europe, you know, especially in the Netherlands tenure isn't,

1206
00:57:00,479 --> 00:57:03,439
you know, it's very likely you'll get tenure, right.

1207
00:57:03,449 --> 00:57:06,600
There's even something that was only recently introduced in some sense, but I've,

1208
00:57:06,610 --> 00:57:08,860
I've never seen people not get tenure.

1209
00:57:08,870 --> 00:57:11,219
So it's, it's not at all like MIT, or Harvard where

1210
00:57:11,479 --> 00:57:13,560
I know half of the people get kicked out or something.

1211
00:57:13,570 --> 00:57:17,100
But then if you're kicked out of Harvard, you still have a great career afterwards,

1212
00:57:17,110 --> 00:57:17,290
right?

1213
00:57:17,300 --> 00:57:19,090
Because you work at Harvard in the first place. So,

1214
00:57:19,959 --> 00:57:20,469
yeah,

1215
00:57:21,030 --> 00:57:23,770
I've never really worried about tenure and all these things.

1216
00:57:23,780 --> 00:57:25,179
I went through the 10 year process in the

1217
00:57:25,189 --> 00:57:27,500
U.S. I just—maybe it's just blissful ignorance.

1218
00:57:27,510 --> 00:57:28,820
I just never worried about it.

1219
00:57:28,830 --> 00:57:32,100
I just, but whatever happened, it happened and just take the next step.

1220
00:57:32,989 --> 00:57:33,469
Um,

1221
00:57:33,600 --> 00:57:35,469
I don't know whether we can give postdoc

1222
00:57:35,919 --> 00:57:39,649
permanent positions because that's not the definition of a postdoc. So,

1223
00:57:40,199 --> 00:57:42,199
what we have done at the University of Amsterdam a

1224
00:57:42,209 --> 00:57:47,649
little bit is to allow people more like flexible contracts.

1225
00:57:47,659 --> 00:57:48,800
Right. So, for instance,

1226
00:57:48,929 --> 00:57:49,760
you could say

1227
00:57:49,909 --> 00:57:52,239
half of my time I'm opposed or half of my time,

1228
00:57:53,080 --> 00:57:55,669
you know, that particular construction doesn't exist, but it's a half time.

1229
00:57:55,679 --> 00:57:56,330
You work

1230
00:57:56,850 --> 00:58:00,139
in a start up, half your time, you work at the university or something like that.

1231
00:58:00,149 --> 00:58:04,139
I think that could be very helpful because half of the time you can make a lot of money,

1232
00:58:04,149 --> 00:58:06,260
you know, working in a start up or a big tech company or whatever

1233
00:58:07,060 --> 00:58:10,239
or run your own business. And then the other half of the time

1234
00:58:10,500 --> 00:58:13,959
you teach or, you know, do research at the university

1235
00:58:14,090 --> 00:58:18,120
that's already incredibly helpful and it doesn't cost university anything. So

1236
00:58:18,639 --> 00:58:21,790
I was going to say that model, is it

1237
00:58:21,909 --> 00:58:23,159
by chance

1238
00:58:23,370 --> 00:58:25,310
or is it something?

1239
00:58:25,449 --> 00:58:28,250
So if you look at an engineering company, look at Boeing, look at Airbus,

1240
00:58:28,320 --> 00:58:29,399
look at Rolls Royce,

1241
00:58:29,770 --> 00:58:31,560
look at Shell, look at almost any

1242
00:58:32,870 --> 00:58:33,320
and I

1243
00:58:33,540 --> 00:58:35,729
don't think there are very many people there

1244
00:58:36,520 --> 00:58:38,080
unless I'm wrong who are,

1245
00:58:39,340 --> 00:58:42,600
let's say their head of their science, but also a professor somewhere else.

1246
00:58:42,870 --> 00:58:45,199
They seem to be purely at that company.

1247
00:58:45,209 --> 00:58:48,399
Whereas I've noticed in tech companies and I guess your

1248
00:58:48,409 --> 00:58:50,560
previous role of Microsoft was an example of that.

1249
00:58:50,899 --> 00:58:52,360
They almost always is a,

1250
00:58:52,760 --> 00:58:53,000
you know,

1251
00:58:53,010 --> 00:58:56,310
extremely distinguished scientists like yourself who also has

1252
00:58:56,320 --> 00:58:59,120
a link to university because it enables them,

1253
00:58:59,879 --> 00:59:03,469
by definition, they, that's how they still become distinguished because,

1254
00:59:03,479 --> 00:59:05,060
you know, they, they're doing their own research.

1255
00:59:05,639 --> 00:59:07,979
Do you think this is a model that should be taken

1256
00:59:07,989 --> 00:59:11,260
more broadly or is it just something unique to the tech world

1257
00:59:11,610 --> 00:59:12,709
with AI? If

1258
00:59:13,000 --> 00:59:14,850
that's the case, I've just noticed this is a,

1259
00:59:14,979 --> 00:59:14,989
a

1260
00:59:15,510 --> 00:59:16,939
trend that,

1261
00:59:17,379 --> 00:59:17,479
yeah,

1262
00:59:17,489 --> 00:59:19,679
we do have some professorships in the Netherlands

1263
00:59:19,689 --> 00:59:21,739
that are one day a week at the university

1264
00:59:22,030 --> 00:59:22,540
um

1265
00:59:23,239 --> 00:59:25,820
that are subsidized by a company. So I think

1266
00:59:26,469 --> 00:59:30,030
it, it does exist a little bit more broadly, of course, in the tech world,

1267
00:59:30,040 --> 00:59:35,010
it gives you also access to the talent pool, which is, which is a very scarce resource

1268
00:59:35,320 --> 00:59:38,300
in AI which may not be the same thing in other companies.

1269
00:59:38,590 --> 00:59:43,370
So that, that's one way in which it's already helpful to have some leg

1270
00:59:43,780 --> 00:59:45,010
in the university.

1271
00:59:45,929 --> 00:59:50,080
Um Yeah, and the other thing is that this field is developing so fast,

1272
00:59:50,090 --> 00:59:52,439
you just need to be at the front,

1273
00:59:52,899 --> 00:59:56,179
you know, you know, frontier of all of that to know what's going on.

1274
00:59:56,189 --> 00:59:59,540
And the best way to do that is to have, you know, to have students and

1275
01:00:00,330 --> 01:00:03,070
you know, let them explain to you what the new trend is, right?

1276
01:00:03,080 --> 01:00:05,159
So it's, it's really important that you're,

1277
01:00:05,449 --> 01:00:06,909
you don't get, you know,

1278
01:00:07,080 --> 01:00:08,000
sort of a,

1279
01:00:08,709 --> 01:00:13,449
how do I say, um, fix it into your own, um, sort of ideology.

1280
01:00:13,500 --> 01:00:15,610
Um But you keep listening to

1281
01:00:16,020 --> 01:00:17,449
young researchers which pick,

1282
01:00:17,459 --> 01:00:20,530
pick up the new trends and want to work on new things and, and you,

1283
01:00:20,540 --> 01:00:22,330
you go with that flow in some sense.

1284
01:00:22,750 --> 01:00:24,830
So I think there's many advantages of having a

1285
01:00:25,139 --> 01:00:26,729
foot in academia

1286
01:00:27,290 --> 01:00:30,449
also for the company where you work for. Uh In fact,

1287
01:00:31,060 --> 01:00:31,520
yeah,

1288
01:00:32,310 --> 01:00:33,719
well, maybe um

1289
01:00:33,850 --> 01:00:36,770
coming, coming to a final question,

1290
01:00:39,040 --> 01:00:43,820
if in term, I think I heard you say in um one of the recent um

1291
01:00:44,110 --> 01:00:45,330
talks that you gave

1292
01:00:46,360 --> 01:00:46,729
that

1293
01:00:47,260 --> 01:00:49,010
you had underestimated

1294
01:00:49,889 --> 01:00:52,270
where machine learning could get to.

1295
01:00:52,560 --> 01:00:53,870
So with that in mind,

1296
01:00:54,290 --> 01:00:56,350
if we were to fast forward five years,

1297
01:00:56,850 --> 01:01:01,679
where do you think we will be at and particularly from the AI for science side,

1298
01:01:02,560 --> 01:01:05,139
do you think there will be a breakthrough,

1299
01:01:05,520 --> 01:01:09,780
huge change almost like, uh, OpenAI did with ChatGPT,

1300
01:01:09,790 --> 01:01:12,060
which sort of sent this inflection point?

1301
01:01:12,250 --> 01:01:13,610
Where do you see

1302
01:01:13,899 --> 01:01:16,020
as being uh in the next few years?

1303
01:01:16,290 --> 01:01:17,340
That's a tough one.

1304
01:01:17,989 --> 01:01:20,939
Predicting the future is always extremely tough. Um

1305
01:01:21,969 --> 01:01:25,229
I do see a very steady improvement and uh this field

1306
01:01:25,239 --> 01:01:28,219
will grow definitely a lot over the next five years.

1307
01:01:28,229 --> 01:01:29,969
So I see, but that's also

1308
01:01:30,139 --> 01:01:30,750
because,

1309
01:01:30,919 --> 01:01:33,050
you know, students need to get interested in it,

1310
01:01:33,209 --> 01:01:34,929
you know, new start ups need to start, you know,

1311
01:01:34,939 --> 01:01:38,250
big tech companies needs to get interested in this, which is what's happening now.

1312
01:01:38,260 --> 01:01:38,760
Um

1313
01:01:39,250 --> 01:01:41,429
And so that field will steadily grow,

1314
01:01:41,820 --> 01:01:44,629
um whether there will be sort of a watershed moment.

1315
01:01:44,969 --> 01:01:45,500
Um

1316
01:01:45,649 --> 01:01:47,340
Now, the reason that happened in,

1317
01:01:47,959 --> 01:01:51,469
you know, in the other field is because there's a lot of data available there.

1318
01:01:51,479 --> 01:01:55,739
Um So I think in some sense, the weather forecasting is a good example of

1319
01:01:56,139 --> 01:02:00,810
a somewhat of a watershed moment. Um where, you know, these models are

1320
01:02:01,239 --> 01:02:01,669
un you know,

1321
01:02:02,070 --> 01:02:04,340
much better than people would have predicted.

1322
01:02:05,139 --> 01:02:05,719
Um

1323
01:02:06,090 --> 01:02:10,540
Now I'm betting myself on materials clearly. Um

1324
01:02:11,010 --> 01:02:11,800
And I think

1325
01:02:12,040 --> 01:02:15,280
my prediction would be that there's going to be enormous

1326
01:02:15,580 --> 01:02:17,919
pool or pressure if you wish

1327
01:02:18,020 --> 01:02:19,669
from society

1328
01:02:19,780 --> 01:02:21,090
to work on,

1329
01:02:21,810 --> 01:02:22,340
you know,

1330
01:02:22,590 --> 01:02:26,139
problems and sustainability because we are running into

1331
01:02:26,149 --> 01:02:28,600
a wall in this whole climate change problem,

1332
01:02:29,229 --> 01:02:31,159
we are still increasing our

1333
01:02:31,600 --> 01:02:33,000
carbon output.

1334
01:02:33,179 --> 01:02:33,729
Um

1335
01:02:33,870 --> 01:02:34,409
you know,

1336
01:02:34,550 --> 01:02:39,000
um since over the last 12% more, over the last five years, something like this. Um

1337
01:02:39,479 --> 01:02:40,530
And there's a lot of

1338
01:02:40,689 --> 01:02:44,850
countries which still have to go through sort of uh industrial revolution almost.

1339
01:02:45,540 --> 01:02:48,919
So I I'm not seeing that politics will solve this.

1340
01:02:49,250 --> 01:02:50,110
Um

1341
01:02:51,580 --> 01:02:55,120
And the problem with this is that it's a shared resource and

1342
01:02:56,429 --> 01:03:00,520
um it, it's, you know, there might be a dynamics where

1343
01:03:01,120 --> 01:03:03,179
by the time it's in your face,

1344
01:03:03,500 --> 01:03:07,169
it's too late because you're past tipping points and all these kinds of things and

1345
01:03:07,350 --> 01:03:08,620
humans have the

1346
01:03:08,969 --> 01:03:10,209
annoying, proper,

1347
01:03:10,320 --> 01:03:11,219
you know, um

1348
01:03:11,969 --> 01:03:11,989
as

1349
01:03:12,090 --> 01:03:16,699
a property of only responding to things when it's right in their face, right?

1350
01:03:16,830 --> 01:03:17,060
You know,

1351
01:03:17,070 --> 01:03:20,870
when the danger is right there in front of you and the lion is there to eat you,

1352
01:03:21,070 --> 01:03:22,620
you know, that's when you run away.

1353
01:03:23,080 --> 01:03:26,479
And so it's very hard to predict and say, oh, this is gonna be tricky, right?

1354
01:03:26,489 --> 01:03:29,010
And so some people do that and some governments even do that.

1355
01:03:29,020 --> 01:03:31,659
But two is that a global scale is incredibly hard.

1356
01:03:32,030 --> 01:03:36,139
Now, what we will see is the impact of climate change, increasing and increasing.

1357
01:03:36,879 --> 01:03:40,860
And that would mean that um this awareness also it's more in your face.

1358
01:03:40,870 --> 01:03:43,550
So it become, you know, the awareness starts to increase as well.

1359
01:03:44,149 --> 01:03:47,219
And that means that people are really going to look for

1360
01:03:47,750 --> 01:03:50,139
solutions in the tech business as well.

1361
01:03:50,149 --> 01:03:50,860
So, you know,

1362
01:03:50,870 --> 01:03:52,830
and there will be more and more investments and more

1363
01:03:52,840 --> 01:03:55,120
and more people will go into that to try to do

1364
01:03:55,510 --> 01:04:01,209
fusion or carbon capture or, you know, uh clean energy, all these kinds of things,

1365
01:04:01,219 --> 01:04:01,500
right?

1366
01:04:01,909 --> 01:04:03,899
And that will accelerate and that's a good thing.

1367
01:04:05,320 --> 01:04:10,639
Um So in that sense, I think we will find amazing new technologies and you know, where

1368
01:04:10,750 --> 01:04:15,219
indeed you you could actually find completely weird new materials that you know,

1369
01:04:15,229 --> 01:04:16,699
weren't imaginable

1370
01:04:17,290 --> 01:04:20,699
some time ago. But now with these new tools, we can actually create them.

1371
01:04:21,520 --> 01:04:22,149
Um

1372
01:04:22,260 --> 01:04:24,399
So I think we'll see amazing things where there's going to

1373
01:04:24,409 --> 01:04:28,330
be an absolutely watershed moment that's really hard to predict.

1374
01:04:29,040 --> 01:04:32,320
Um But um yeah, I, I do think

1375
01:04:32,790 --> 01:04:33,820
that with the new

1376
01:04:34,030 --> 01:04:38,699
technology that we're building in AI um and maybe quantum computing as well uh in,

1377
01:04:38,770 --> 01:04:40,520
you know, 5 to 10 years,

1378
01:04:40,739 --> 01:04:45,649
this field will accelerate and, and, and, and produce very exciting results. Yeah.

1379
01:04:45,949 --> 01:04:48,020
Do, do you feel almost that um

1380
01:04:49,179 --> 01:04:50,479
one person told me

1381
01:04:51,139 --> 01:04:52,800
we've globally

1382
01:04:53,520 --> 01:04:56,889
tech companies and start ups have hired so many people

1383
01:04:57,310 --> 01:04:59,250
to work on large language models.

1384
01:05:00,010 --> 01:05:02,699
Do we almost need to wait for that to plateau for

1385
01:05:02,709 --> 01:05:05,969
all those staff to then be given another direction to work on

1386
01:05:06,159 --> 01:05:10,229
and then they can double down more on the scientific problems where for now,

1387
01:05:10,239 --> 01:05:14,239
I guess most companies are trying to chase the current goal, which is,

1388
01:05:14,570 --> 01:05:15,129
you know,

1389
01:05:15,260 --> 01:05:19,159
the the large language model type thing. Do, do you feel there's also a little bit of a

1390
01:05:19,379 --> 01:05:22,120
resourcing and pivotal moment that

1391
01:05:22,260 --> 01:05:23,649
we need to shift

1392
01:05:23,889 --> 01:05:25,320
to focus on the science

1393
01:05:25,459 --> 01:05:27,199
or can they be be done in parallel?

1394
01:05:27,429 --> 01:05:28,639
Um I think they

1395
01:05:28,790 --> 01:05:32,399
have to be done in parallel because I have no illusions that um

1396
01:05:32,699 --> 01:05:37,840
you know, AGI will be pursued hotly by all these big companies because it's just,

1397
01:05:37,989 --> 01:05:38,459
I don't know,

1398
01:05:39,489 --> 01:05:43,659
you can make too much money if you find that, you know, this is too uh

1399
01:05:44,570 --> 01:05:45,090
um

1400
01:05:46,110 --> 01:05:46,669
you know, you can,

1401
01:05:46,929 --> 01:05:49,310
how do you say too lucrative to, to not do it.

1402
01:05:49,909 --> 01:05:50,449
Um

1403
01:05:50,790 --> 01:05:53,429
But I think there is also a lot of talent in the market

1404
01:05:53,679 --> 01:05:56,969
and I have found that a lot of young people in particular,

1405
01:05:57,060 --> 01:06:00,330
they want to do something that is meaningful with their life.

1406
01:06:00,870 --> 01:06:06,290
And it's that subset of people that can align their goals in life, you know,

1407
01:06:06,399 --> 01:06:09,129
contributing meaningfully to society with their talent

1408
01:06:09,459 --> 01:06:10,530
and make a good,

1409
01:06:10,669 --> 01:06:11,169
you know,

1410
01:06:11,520 --> 01:06:12,350
salary

1411
01:06:12,479 --> 01:06:14,250
on the side. And so I think

1412
01:06:14,510 --> 01:06:16,909
there will be an increasing group of people who want

1413
01:06:16,919 --> 01:06:19,530
to pursue these kinds of goals rather than work on

1414
01:06:19,810 --> 01:06:22,050
advertisement placement or something like that.

1415
01:06:23,649 --> 01:06:25,780
Well, yeah, I, I agree. I, I hope so.

1416
01:06:25,790 --> 01:06:29,149
I think uh it's amazing what machine learning has been able to achieve.

1417
01:06:29,159 --> 01:06:31,000
But I agree that if we could

1418
01:06:31,189 --> 01:06:31,780
um

1419
01:06:32,929 --> 01:06:36,669
push all that knowledge and that amazing thing to

1420
01:06:36,879 --> 01:06:41,790
things that will help the world and society and the average individual,

1421
01:06:41,800 --> 01:06:44,909
then I think that will be seen as a very positive

1422
01:06:45,060 --> 01:06:47,590
outcome from all this rather than, as you said,

1423
01:06:48,679 --> 01:06:51,560
things that are maybe still useful, but

1424
01:06:51,719 --> 01:06:52,899
maybe less

1425
01:06:53,580 --> 01:06:56,689
an impact on society and on climate change. So,

1426
01:06:57,590 --> 01:07:00,330
thank you so much. I know you're a very busy man.

1427
01:07:00,340 --> 01:07:01,889
So I appreciate you taking the time to speak.

1428
01:07:01,899 --> 01:07:04,229
I certainly learned a lot and I found it very interesting.

1429
01:07:04,239 --> 01:07:05,850
So, yeah, thank you so much.

1430
01:07:06,020 --> 01:07:08,330
My pleasure, Neil. It was, it was really fun talking to you

1431
01:07:30,770 --> 01:07:30,800
that
