You know why I use that, though? I'll tell you why. Why my brain went there is because anybody that gets an education in physics has this sort of trope about how all the great physicists did their best work in their 20s. And then you don't do any good work after that. And I always thought it was kind of funny because for me, physics is not complete.

It's not nearly complete, but most physicists think that we understand most of the structure of reality. And so I think I actually, I think I put this in the book somewhere, but like this idea to me that societies would discover everything while they're young is very consistent with the way we talk about physics right now. But I don't think that's actually the way that things are going to go.

And you're finding that people that are making major discoveries are getting older in some sense than they were. And our lifespan is also increasing. So I think there is something about age and your ability to learn and how much of the world you can see that that's really important over a human lifespan, but also over the lifespan of societies. And so I don't know how big the frontier is.

I don't actually think it has a limit. I don't believe in infinity as a physical thing, but I think as a receding horizon, I think because the universe is getting bigger, you can never know all of it.

And I don't. I mean, not that I believe in infinities, but I don't, I think the size of the book is growing.
