The Ledger, every show

“Space is discrete. There are atoms of space, so to speak, not like physical atoms like hydrogen, helium, and things.”

“Time is a computational phenomenon. Time is the progressive change of the network.”

“And it turns out that exact same phenomenon is the origin of space-time and gravity, that these, all these atoms of space operating in this network, it's all this computationally irreducible process, but observers like us, observers who are computationally bou…”

“So we kind of have this trade off. We either can understand what's going to happen, in which case we don't let our AIs really do what they can do, or we always say, okay, we're going to run the risk of the AI doing something unexpected.”

“So this principle of computational equivalence says, whether you have a brain or a computer or mathematics or statistics or whatever else, you are really just equivalent in your computational sophistication to the system that you're trying to predict. And that…”

“When you ask the question in the space of sort of all possible concepts, how many do we have words for? The answer is it's one in 10 to the 600.”

“And so, you know, imagine sort of the alien that isn't like us, that isn't computationally bounded, doesn't believe it's persistent in time. It will observe different laws of the universe.”

“Yeah, I think AI is sort of, AI is very limited in the computational universe.”

“It has been assumed that electrons are actually infinitesimally small, but that doesn't seem to be true.”
