The simulation hypothesis as you have stated it is an argument for materialism. A simulation on one of our (conventional) computers is a bunch of particles moving through CPU and GPU processors and LED pixels. One running on some future quantum computer would be using qubit chips. What is the computer the advanced alien civilization is running "us" on? It could be in fact "our" universe as quantum computer [ https://arxiv.org/abs/1312.4455 ]! Then we would be a bunch of particles running on the advanced alien civilization 's quantum computer, just as simulations above ore particles running on one of our quantum computers. - pt -- You received this message because you are subscribed to the Google Groups "Everything List" group.
