Of course, there's the question of things like chaotic systems where the initial conditions really matter and then you get to some, you know, uncorrelated end state.

Now, those could be difficult to model.
Lex Fridman Podcast
#475 โ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games
So I think these are kind of the open questions.
Lex Fridman Podcast
#475 โ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games
But I think when you step back and look at what we've done with the systems and the problems that we've solved, and then you look at things like VO3 on like video generation, sort of rendering physics and lighting and things like that, you know, really core fundamental things in physics.
Lex Fridman Podcast

It's pretty interesting.
Lex Fridman Podcast
#475 โ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games
I think it's telling us something quite fundamental about how the universe is structured, in my opinion.

So, you know, in a way, that's what I want to build AGI for, is to help us as scientists answer these questions like P equals MP.

And so if there's one to follow and you can specify the objective function correctly, you know, you don't have to deal with all that complexity, which I think is how we maybe have naively thought about it for decades, those problems.

If you just enumerate all the possibilities, it looks totally intractable.
Lex Fridman Podcast
#475 โ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games
And there's many, many problems like that.
Lex Fridman Podcast
#475 โ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games
And then you think, well, it's like 10 to the 300 possible protein structures, 10 to the 170 possible go positions.

All of these are way more than atoms in the universe.
Lex Fridman Podcast
#475 โ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games
So how could one possibly find the right solution or predict the next step?
Lex Fridman Podcast
#475 โ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games
But it turns out that it is possible.
Lex Fridman Podcast
#475 โ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games
And of course, reality in nature does do it.
Lex Fridman Podcast
#475 โ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games
right?
Lex Fridman Podcast
#475 โ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games
Proteins do fold.

So that gives you confidence that there must be, if we understood how physics was doing that, in a sense, then, and we could mimic that process, i.e.

model that process, it should be possible on our classical systems is basically what the conjecture is about.
Lex Fridman Podcast
#475 โ Demis Hassabis: Future of AI, Simulating Reality, Physics and Video Games
Yes, exactly.
