You are where your attention is. If you’re watching a football game with your son while also texting a friend, you’re not fully with your child — and he knows it. Truly being with another person means being experientially with them, picking up countless tiny signals from the eyes and voice and body language and context, and reacting, often unconsciously, to every nuance. These are our deepest social skills, which have been honed through the aeons. They are what make us distinctively human.
By rapidly substituting virtual reality for reality, we are diminishing the scope of this interaction even as we multiply the number of people with whom we interact. We remove or drastically filter all the information we might get by being with another person. We reduce them to some outlines — a Facebook “friend,” an Instagram photo, a text message — in a controlled and sequestered world that exists largely free of the sudden eruptions or encumbrances of actual human interaction. We become each other’s “contacts,” efficient shadows of ourselves.
