It kind of irks me that they basically assume a cubic lattice. Nature does not form cubic lattices, when nature forms a lattice (for example, in a foam) it tends to form roughly dodecahedral cells (with coordination number 12). Given this property, a space-time lattice would be very nearly isotropic.

QED. It's not nature, just a cubic simulation of nature. Otherwise known as The Matrix :)

It kind of irks me that they basically assume 3+1- space-time.

If we're living in a simulation, the question of whether AIs can have consciousness is solved.

What if there is a rule in the simulation preventing intelligences created by simulants from becoming sentient?

I suppose you can point at all the artificial simulants and their sentience, but as pointed out in a sibling comment, so what.

Keep in mind that if you wanted to create a simulated universe you can ensure nobody ever finds out.

If someone does find out, you can simply fix the problem and revert to a point in time just before the data leading to the discovery was captured.

Speaking academically, you might be playing with fire if you probe the outer limits of the universe and we are in a simulation run by some entity concerned with keeping that a secret.

What sort of moral issues result from creating a simulation universe that gives rise to sentient beings? I feel creeped out and reminded of Source Code with Jake Gyllenhaal for some reason.

That's assuming sentience is an emergent property of the simulation rather than something else, such as being the ground from which the simulation arises from.

While you're largely right, salt disagrees.
