A million reasons we're not in a simulation, off the top of my head: - What are the physics of the simulator? A simulation solves no problems, it just kicks the problem of explaining physics up a level, accomplishing nothing. You may as well say that the earth rests on turtles. - We live in a simulation? Fantastic. It’s actually a simulation that’s run by dogs. No, it's run by insects. No, it's run by Zeus. The argument is infinitely variable and worthless. - There is apparently a stochastic argument for simulation. There are no stochastic processes in the universe, period. Stochastic processes require physics that support them and there are no known random physical processes in the (multi)universe. - Simulation advocates imagine that the simulator is just another Turing machine. Why would it be a Turing machine? Why would it be the same exact technology that we already have in this universe? At least use your imagination to come up with a different kind of computer, which will be yet another infinitely variable argument. - Apparently there is experimental evidence of a simulator. Has it been reproduced? No? Great, it is garbage. Goodbye!
