The caveat here is, even if we are a computational (or some other) process in some system, that doesn't mean that process is a simulation of another process. Ju

The caveat here is, even if we are a computational (or some other) process in some system, that doesn't mean that process is a simulation of another process. Just because there's a system A that "wraps" system B, doesn't mean that system B's processes can be called "simulations" -- simulation implies that there's a process in system A that the process in system B is trying to mimic.
