06:04
06:04>> Yeah. Well, look, RSI uh it's obviously
06:08
06:08an extremely uh useful technique to make
06:12
06:12progress. It mostly works best in what I
06:15
06:15call verifiable domains, what's called
06:17
06:17verifiable viable domains. So, um math
06:20
06:20is one, which is why we're seeing so
06:22
06:22much advance there. Coding's another um
06:24
06:24but originally it was games. Actually,
06:26
06:26one of the first sort of famous
06:28
06:28recursive self-improving systems was one
06:30
06:30we invented quite a lot of years ago now
06:32
06:32called Alpha Zero, which was off the
06:34
06:34back built off the back of Alph Go,
06:36
06:36which was the kind of, you know, famous
06:38
06:38program that beat the world champion at
06:40
06:40Go back in 20, you know, 10 years ago
06:42
06:42now, 2016, and kind of was the
06:44
06:44beginning, I think, of the modern AI
06:46
06:46era. And then we built a second version
06:48
06:48that was in some ways more
06:49
06:49consequential, Alpha Zero, that didn't
06:52
06:52need to use any human data anymore. And
06:55
06:55um it just basically played against
06:56
06:56itself. Started at random and then you
06:59
06:59know around a dozen to two dozen
07:01
07:01different epochs. You know it play like
07:03
07:03a million games against itself. Uh it
07:05
07:05would then train a new version of itself
07:08
07:08uh uh that was slightly better than the
07:10
07:10old version and then that would play a
07:12
07:12million games against itself and so on
07:14
07:14and and for example and then it could
07:15
07:15play any game not just go it could play
07:18
07:18any two-player perfect information game.
07:20
07:20And for me it was especially visceral as
07:22
07:22a chess player because I remember
07:24
07:24watching it play chess and within um you
07:28
07:28know 12 hours basically or less than 12
07:31
07:31hours it would start from random play in
07:33
07:33the morning to you know you'd have your
07:35
07:35coffee break at 11:00 a.m. and I could
07:37
07:37still just about beat it. Then by
07:39
07:39lunchtime it was grandmaster level and
07:41
07:41then by by tea time it was better than
07:44
07:44um the any any chess playing entity.
07:46
07:46time is dinner time for the US computer
07:48
07:48time to you know or computer you know
07:51
07:51kind of handcrafted chess computer is
07:53
07:53better than all of them so we sort of
07:56
07:56saw the power of that recursive
07:58
07:58self-improvement and obviously the thing
07:60
07:60that all these domains have in common is
08:01
08:01you can verify the answer is it cor is
08:04
08:04it a correct answer is it an optimal
08:05
08:05answer is the equation correct it does
08:07
08:07the code run it did you win the game and
08:10
08:10the important thing about a verifiable
08:11
08:11domain is you can verify the answer um
08:13
08:13so you know when you've you've you
08:15
08:15you've you've hit the by point. Um, but
08:17
08:17also that means you can create almost
08:19
08:19infinite synthetic data because you can
08:22
08:22just use the current best versions you
08:24
08:24have to set new problems or make new
08:26
08:26moves and then um uh just sort of verify
08:30
08:30uh uh whether the synthetic data was
08:32
08:32correct. The problem with synthetic data
08:34
08:34a lot of the time is you can't verify
08:35
08:35that it's right um from the right
08:37
08:37distribution but in these cases you can.
08:40
08:40So we've seen the enormous progress with
08:42
08:42maths and with um coding and coding's
08:45
08:45obviously become enormously valuable and
08:47
08:47everyone is having to do that now. But I
08:50
08:50do worry about it because in the limit
08:52
08:52so there's different forms of RSI right
08:54
08:54now. We're in the the early days of RSI
08:57
08:57I would say where what's happening is
08:59
08:59and you're probably all experiencing
09:00
09:00this as well with your teams is um you
09:03
09:03know it's making a human engineer maybe
09:06
09:06three, four, five times more productive.
09:09
09:09Okay. So, uh but the but the human is
09:11
09:11very much still in the loop and
09:13
09:13reviewing code and architecting things
09:15
09:15and um and and and writing code still.
09:18
09:18Um but it's all just enhanced. Um the
09:21
09:21next phase which I think carries the
09:23
09:23most risk is closed RSI closed loop
09:26
09:26where you basically manage to somehow
09:28
09:28figure out how to do it without the
09:29
09:29human reviewer process uh in this in the
09:32
09:32in the whole procedure and that um will
09:35
09:35obviously be faster but I think is also
09:37
09:37a very dangerous way to get to full AGI
09:40
09:40because we're likely for two reasons
09:42
09:42it's it's sometimes used to be referred
09:44
09:44to 20 years ago as like an intelligence
09:46
09:46explosion because you don't quite know
09:48
09:48uh how you know how do you control keep
09:51
09:51control of such a system uh such a
09:53
09:53process and then the end result will
09:56
09:56likely be quite alien. It's going to be
09:57
09:57like an alien intelligence. There's no
09:59
09:59reason you to think it would be sort of
10:01
10:01in the similar kind of mind space that
10:04
10:04uh humans are in. So that will make it
10:06
10:06very hard for it to understand for us to
10:08
10:08understand it and maybe for it to
10:09
10:09understand us. So I think it's you know
10:12
10:12we should be very cautious as we get
10:14
10:14closer towards that closed loop form of
10:16
10:16RSI and I think all the AI researchers
10:19
10:19sort of know that but there is a sort of
10:21
10:21race to the there's this sort of intense
10:23
10:23obviously uh uh uh competitive race to
10:27
10:27improve your coding systems. So presume
10:29
10:29that the the incentives to be in a race
10:33
10:33continue and you know you and I some
10:35
10:35people really know this you know have
10:37
10:37tried to figure out if there's various
10:38
10:38ways you can get global collaboration to
10:40
10:40you've dedicated a huge amount of energy
10:42
10:42to that so thank you um uh it's a hard
10:45
10:45game as you know but presume that the
10:47
10:47competitive pressure for continuing to
10:50
10:50do RSI and coding continues
