So far especially enjoying the focus on different levels of simulation resolution. The autoverse is a biology simulation with simplified atoms (or does that make it physics). While the simulation where people are being copied into operates at the level of organs. Thinking about how that compares to our current simulations... I think there is very little effort to build up out from atoms, right? Light simulations do simulate raycasting - a move towards the actual physical process. Would world simulations trend the same way - it would just be so much computing power! And what about LLMs. There's influence from neurons, and certainly about going from flexible, lower-level objects to produce emergent behavior. But the fact that it's operating in/on language... kind of by default means its higher-level? It's baking in language concepts unless it generalizes to the lower-level concepts from them...
