#472 โ€“ Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

Now give me a rate.

Okay, so if I don't have an infinite number of monkeys, but a large finite number of monkeys, how long do I have to wait for Hamlet to come out?

Lex Fridman Podcast
#472 โ€“ Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

And that's a more quantitative question.

Lex Fridman Podcast
#472 โ€“ Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

And this is something that you can attack by purely finite methods, and you can use your finite intuition.

And in this case, it turns out to be exponential in the length of the text that you're trying to generate.

And so this is why you never see the monkeys create Hamlet.

Lex Fridman Podcast
#472 โ€“ Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

You can maybe see them create a four-letter word,

Lex Fridman Podcast

but nothing that big.

Lex Fridman Podcast
#472 โ€“ Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

And so I personally find once you finalize an infinite statement, it does become much more intuitive and it's no longer so weird.

Lex Fridman Podcast
#472 โ€“ Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

Yeah.

Lex Fridman Podcast

The downside is that the finalized proofs are just much, much messier.

Lex Fridman Podcast
#472 โ€“ Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

So the infinite ones are found first, usually, like decades earlier.

Lex Fridman Podcast
#472 โ€“ Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

And then later on, people finalize them.

Lex Fridman Podcast
#472 โ€“ Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

Right.

Lex Fridman Podcast

So I think science in general is interaction between three things.

Lex Fridman Podcast
#472 โ€“ Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

There's the real world.

Lex Fridman Podcast
#472 โ€“ Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

There's what we observe of the real world, our observations.

Lex Fridman Podcast
#472 โ€“ Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

and then our mental models as to how we think the world works.

Lex Fridman Podcast
#472 โ€“ Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

So we can't directly access reality.

Lex Fridman Podcast
#472 โ€“ Terence Tao: Hardest Problems in Mathematics, Physics & the Future of AI

All we have are the observations, which are incomplete, and they have errors.
