Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

And it sort of fits with the way I think about physics in general, which is that, you know, I think information is primary.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

Information is the most sort of fundamental unit of the universe, more fundamental than energy and matter.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

I think they can all be converted into each other.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

But I think of the universe as a kind of informational system.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

That's right.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

Yeah, I think it's one of the most fundamental questions, actually, if you think of physics as informational.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

And the answer to that, I think, is going to be very enlightening.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

Yeah, I think that there are actually a huge class of problems that could be couched in this way, the way we did AlphaGo and the way we did AlphaFold, where you model what the dynamics of the system is, the properties of that system, the environment that you're trying to understand, and then that makes the search for the solution or the prediction of the next step efficient.

#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

basically polynomial time, so tractable by a classical system, which a neural network is.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

It runs on normal computers, classical computers, Turing machines in effect.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

And I think it's one of the most interesting questions there is, is how far can that paradigm go?

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

I think we've proven, and the AI community in general, that classical systems, Turing machines, can go a lot further than we previously thought.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

They can do things like model the structures of proteins and play Go to better than world champion level.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

And a lot of people would have thought maybe 10, 20 years ago, that was decades away, or maybe you would need some sort of quantum machines to quantum systems to be able to do things like protein folding.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

And so I think we haven't really even sort of scratched the surface yet of what classical systems so-called could do.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

And of course, AGI being built on a neural network system, on top of a neural network system, on top of a classical computer would be the ultimate expression of that.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

And I think the limit, you know, what the bounds of that kind of system, what it can do, it's a very interesting question and directly speaks to the P equals NP question.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

Yeah, I think those systems would be right on the boundary, right?

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

So I think most emergent systems, cellular automata, things like that could be modelable by a classical system.

Lex Fridman Podcast
#475 โ€“ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games

You just sort of do a forward simulation of it and it'd probably be efficient enough.
