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

If I want to describe electricity and magnetism in the 1800s, I have to have waves be fundamental, right? So like you are in quantum mechanics, like it's a wave function that's fundamental because that's the sort of explanatory paradigm of your theory, right? So I guess I don't know what problem saying computation is fundamental solves.

Well, I think that the issue is general relativity and quantum mechanics are expressed in mathematical languages. Mm-hmm. And then computation is a mathematical language. So you're basically saying that maybe there's a more universal mathematical language for describing theories of physics that we already know. That's an important question.

And I do think that's what Stephen's trying to do and do well. But then the question becomes, does that formulation of a more universal language for describing the laws of physics that we know now tell us anything new about the nature of reality? Or is it a language? Yeah.

The language itself is never the fundamental thing. It's whatever it's describing.

I think if assembly theory is an accurate depiction of the physics of life, it should shed a lot of light on those problems. And in fact, I sometimes wonder if the problems of consciousness and intelligence are at all different than the problem of life generally.

And I'm of two minds of it, but I in general try to, you know, like the process of my thinking is trying to regularize everything into one theory. So pretty much every interaction I have is like, oh, how do I fold that into? And like, so I'm just building this giant abstraction that's basically trying to take every piece of data I've ever gotten in my brain into a theory of what life is.

And consciousness and intelligence are obviously some of the most interesting things that life has manifest. And so I think they're very telling about some of the deeper features about the nature of life.

Like this use of flavors, the same as you meant when you were talking about flavors of alien life.
