I find these philosophy thought exercises profoundly useless. Even if copying a brain into a simulator, surgically replacing the brain with the simulator without the host noticing and without secondary effects, was somehow possible, they give the same vibe as "imagine an infinite rope", "imagine a perfectly spherical cow", etc. They're fun for discussing while having a few beers with your friends, but they don't help solve the problem they think they're helping solve.
