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

So it's the fact that you're a deterministic structure living in a random background. And also all of that selection bundled in you allows you to select on possible futures. So that's where your will comes from. And there's just always a little bit of randomness because the universe is getting bigger.

And, you know, like this idea that the past is and the present is not large enough yet to contain the future. Right. The extra structure has to come from somewhere. And some of that is because outside of those giant causal structures that are things like us, it's fucking random out there. And it's scary.

And we're all hanging on to each other because the only way to hang on to each other, like the only way to exist is to like cling on to all of these causal structures that we happen to co-inhabitate existence with and try to keep reinforcing each other's existence.

Well, it's also โ€“ it's not just the randomness. There's two features. One is randomness helps generate some novelty and some flexibility. But it's also that, like, because you're the structure that's deep in time, you have this combinatorial history that's you. And I think about time and assembly theory not as linear time but as combinatorial time.

So if you have all of this structure that you're built out of, you โ€“ in principle, you know, your future can be combinations of that structure. You obviously need to persist yourself as a coherent you. So you want to optimize for a common, like a, a future in that combinatorial space that still includes you most of the time for most of us.

And, and when you make those kinds of, and then that gives you a space to operate in and that's your sort of horizon where your free will can operate. And your free will can't be instantaneous.
