That said, there's something quite narrow minded in a lot of the arguments for the plausibility of the idea that we live in a simulation. (1) Why does the simulator have to exist in a universe that is anything like ours? Their physics doesn't have to be anything like ours, so discussion of how we might find evidence that we're in a simulation breaks down. (2) Nonetheless, this "discussion of how we might find evidence that we're in a simulation" does demonstrate that we'll never have enough computing power in this universe to run a sufficiently thorough simulation of a universe containing human-level intelligence.
Conclusion: we're at the bottom.
