That is why I have doubts about their scalability. There are fundamental physics reasons we were able to scale digital computers and were unable to do the same to analog ones.
Wouldn’t you be able to run a higher clock-speed simulation, and therefore compute the sound ahead-of-time, on a digital device?
But there is some hypothesis like MUH that sees reality as a sort of "recording" that we just experience.
Why? because the "universe" takes zero time to compute it. In fact all of reality is computed in zero time. How can you beat it?
I think it is totally possible for the computing to take non-zero time, but we observe it in zero-time as our consciousness only steps forward only with each iteration of computing the world state. So we observe zero time reality computations.
