It seems rather ontologically extravagant. I think they're vastly underestimating the amount of computing power it would take to seamlessly simulate a universe.

It seems rather ontologically extravagant. I think they're vastly underestimating the amount of computing power it would take to seamlessly simulate a universe. Still, there's one way to test the simulation hypothesis: build our own planet-sized universe-simulating computer and see if our own universe has a segfault.
