The only problem with the simulation hypothesis is that it's unlikely that we're aliens wearing a TentacleVR hat and when our human character dies we take it off and go about our alien day.

It's very likely that the simulators don't even know we exist, or even that life exists, in their simulation. They're simulating universes with different constants or something like that.

That's why I don't like these attempts to do insane computations with quantum. If they can actually do classical computations that would take longer than the universe then maybe we crash the simulator or they restart it to fix the glitch.
