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

I think there's a horizon, and I don't know how to articulate this yet. It's a little bit like the horizon at the origin of life, where the space inside a particular structure becomes so large that it has some access to a space that's not... That doesn't feel as physical. It's almost like this idea of counterfactuals.

So I think like the past history of your horizon is just much larger than can be encompassed in like a small configuration of matter. So you can like pull this stuff into existence. This property is maybe a continuous property, but there's something really different about human level physical systems and human level ability. to understand reality.

I really love David Deutsch's conception of universal explainers, and that's related to the theory of universal computation. And I think there's some transition that happens there. But maybe to describe that a little bit better, what I can also say is what intelligence is in this framework. So you have these objects that are large in time,

they were selected to exist by constraining the possible space of objects to this particular, like all of the matter is funneled into this particular configuration of object over time. And so these objects arise through selection, but the more selection that you have embedded in you, the more possible selection you have on your future. And so the

selection and evolution we usually think about in the past sense, where selection happened in the past. But objects that are high density configurations of matter that have a lot of selection in them are also selecting agents in the universe. So they actually embody the physics of selection and they can select on possible futures.

And I guess what I'm saying with respect to consciousness and the experience we have is that there's something very deep about that structure and the nature of how we exist in that structure that has to do with how we're navigating that space and how we generate that space and how we continue to persist in that space.

I mean, I think they already do, but not in the way I hear popularly discussed. So there are obviously signatures of intelligence and... and a part of a ecosystem of intelligent systems. But I don't know that individually, you know, I would assign all the properties to them that people have.

It's a little like, so, you know, we talked about the history of eyes before and like how eyes scaled up into technological forms. And language has also had a really interesting history and got much more interesting, I think, once we started writing it down. And then, you know, inventing books and things.
