Yes.

#433 โ€“ Sara Walker: Physics of Life, Time, Complexity, and Aliens

But this is why I'm okay with having a finite lifetime. And, you know, one of the reasons I'm okay with that, actually, goes back to this issue of the fact that we're resource-bound. We live in a... You know, like, we have a finite amount of material, whatever way you want to define material. I think, like, for me, you know, material is time. Material is information.

But we have a finite amount of material. If time is a generating mechanism, it's always going to be finite because... The universe is, you know, like it's a resource that's getting generated, but it has a size, which means that all the things that could exist don't exist. And in fact, most of them never will.

So death is a way to make room in the universe for other things to exist that wouldn't be able to exist otherwise. So if the universe over its entire temporal history wants to maximize the number of things, wants is a hard word, maximize is a hard word, all these things are approximate, but It wants to maximize the number of things that can exist.

The best way to do it is to make recursively embedded stacked objects like us that have a lot of structure and a small volume of space and to have those things turn over rapidly so you can create as many of them as possible.

I think we're in our 20s. 20% of the 20s? No, like age-wise, let's say. We're in our 20s, but the lifespan is going to keep getting longer.

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.
