And I think it's a really important missing piece.

The ability to plan and reason more generally across a wide variety of different settings.

Yeah.

So you can kind of think of it as like neural nets today.

They'll give you, like Transformers, for example, are super general.

But, you know, they'll give you, it'll output an answer in like 100 milliseconds.

And if you tell it like, oh, you've got five minutes to give you a decision, you know, feel free to take more time to make a better decision.

It's not going to know what to do with that.

But a human, if you're playing a game like chess, they're going to give you a very different answer depending on if you say, oh, you've got 100 milliseconds or you've got five minutes.

Yeah, they got this thing called chain of thought reasoning.

Yeah, and I think it's a good step in the right direction.

I would kind of say it's similar to Monte Carlo rollouts in a game like chess.

There's a kind of search that you can do where you're saying, I'm going to roll out my intuition and see without really thinking, what are the better decisions I can make farther down the path?

What would I do if I just acted according to intuition for the next 10 moves?

And that gets you an improvement, but I think that there's much richer kinds of planning that we could do.

Yeah, the Libratus competition was super stressful for me.

Also, I mean, I was working on this like basically continuously for a year leading up to the competition.

I mean, for me, it became like very clear, like, okay, this is the search technique.

This is the approach that we need.

And then I spent a year working on this pretty much like nonstop.
