> You can isolate it in this way or that way, but you cannot entirely prevent interaction with the outside world. The mere fact of some interaction happening does not automatically let you answer the question whether you're in a simulation or not. The whole point of simulations where you can inspect them from the outside is some kind of interaction, but it doesn't mean that an entity inside the simulation is able to determine what's going on outside. Just that the simulation is observable makes it not isolated in the sense that you're using, so yes, you're right, but at the same time it's not very relevant to what I was talking about. A simulated Game of Life field isn't isolated either.
