The programmers of that simulation could be cheating a bit. For example, they could approximate the movement of particles by using wave fields, and only if the particles are observed, would it actually simulate individual particles.
It would cause some weird effects that shouldn’t be there. For example a light spot in the middle of circular shadows. But most players don’t want 100% perfection. They want to be able to run the game on their device.







Yes. My thoughts and feelings matter. But if it’s simulated with a few shortcuts, your thoughts and feelings might not exist.
Maybe all other humans are only about as well-simulated as current LLMs.
