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

I hope next one.

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

It won't happen this IMO.

Lex Fridman Podcast

The performance is not good enough in the time period.

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

But there are smaller competitions.

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

There are competitions where the answer is a number rather than a long-form proof.

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

And AI is actually a lot better at problems where there's a specific numerical answer.

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

Because it's easy to reinforce learning on it.

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

Yeah, you got the right answer, you got the wrong answer.

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

It's a very clear signal.

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

But a long-form proof either has to be formal, and then the lean can give it thumbs up, thumbs down.

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

or it's informal, but then you need a human to grade it.

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

And if you're trying to do billions of reinforcement learning runs, you can't hire enough humans to grade those.

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

I mean, it's already hard enough for the last language learners to do reinforcement learning on just the regular text that people get.

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

But now if you hire people and not just give thumbs up, thumbs down, but actually check the output mathematically, yeah, that's too expensive.

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

That's a good question.

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

I think the nature of what mathematicians do over time has changed a lot.

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

You know, so a thousand years ago, mathematicians had to compute the date of Easter, and those really complicated calculations, you know, but it's all automated, been automated for centuries.

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

We don't need that anymore.

Lex Fridman Podcast

They used to do spherical trigonometry to navigate how to get from the old world to the new.

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

Very complicated calculations.
