I do wonder if you'd want to implement a sort of 3D game engine that simulates the entire universe, if somehow the weird stuff quantum physics and general relativity do (like the planck limit, the lightspeed limit, discretization, the 2D holographic bound on amount of stuff in 3D volumes, the not having an actual value til measured, the not being able to know momentum and speed at the same time, the edge of observable universe, ...) will turn out to be essential optimizations of this engine that make this possible.
Many of the quantum and general relativity behaviors seem to be some kind of limits (compared to a newtonian universe where you can go arbitrarily small/big/fast/far). Except quantum computing, that one's unlocking even more computation instead so is the opposite of a limit and making it harder rather than easier to simulate...
I don’t think the “not having an actual value until measured”, properly understood, would seem like an optimization.
I don’t know why so many people feel like it would be an optimization?
Storing a position is a lot cheaper than storing an amplitude for each possible position.
One-hot vectors are much more compressible than general vectors, as you can just store the index.
Also, it is momentum and position that are conjugate, not momentum and speed.
