A week ago or so, i told people to try an experiment to see if we live ina simulation. If you were sim what would you be able to think about? See, it would be really hard to programme us to be like people. But knowing that you in a simulation could actually change your behaviour, at least opens the possibility that you can program it. This disimulating computer must be exactly the size of the universe, incorrect. It might not even make it impossible for some higher-level computers to do simulations. The system doesn't need to keep the story straight in the past e.g. Aevery explanation of existence is irrelevant unless it changes how you act in the
