>basically their arguments are arguing for the argument that no "real world" exists or is even theoretically possible
That's not Nick's argument, though. His argument is that if (1) and (2) are false, then our universe is most likely (but not certainly) a simulation, because any universe with the scale of ours in which (1) is false is going to develop many intelligent life forms more advanced than us in our present state, and if (2) is false, then that means such life forms, with the ability to harness massive amounts of energy (e.g. with Dyson spheres or something equivalent), will simulate mini-universes down to consciousness. It does imply that in such a scenario, any random universe experienced by a conscious being is extremely likely to be a simulation, but inevitably one would be real. Hence "almost certainly". Energy would remain a limiting factor preventing an infinity Matryoshka doll of nested universes, since if we're a simulation, we can be confident that the basic rules of physics observed in this universe apply in the real one that is simulating it. If they didn't, it wouldn't be much of a simulation.

>>As long as the simulation follows consistent rules, there's no difference between living a simulation and a computable universe.
This is right, which is why it's of little comfort when it comes to existential dread.
