Nima Arkani-Hamed: The End of Space-Time [video]

I am curious if there is any "serious" discussion within this domain, about the simulation hypothesis.

Naively, it certainly *seems* like a lot of the properties of our own universe are consistent with those one would expect from a simulated one... I am thinking specifically of eg uncertainty and "local reality"; and, absolute limits on the speed of information propagation; and even perhaps general relativity—many such things seem naturally emergent from a computed universe.

I have found it puzzling that this is not more generally discussed; I'm not sure if that's because it's considered obviously false, or, obviously true, or, irrelevant ("metaphysics") when the task at hand is just characterization of what we're living with.

I don't think he gave enough information to know whether what he says helps progress physics just that it exists.
