Most of our communication technologies began as diminished substitutes for an impossible activity. We couldn’t always see one another face to face, so the telephone made it possible to keep in touch at a distance. One is not always home, so the answering machine made a kind of interaction possible without the person being near his phone. Online communication originated as a substitute for telephonic communication, which was considered, for whatever reasons, too burdensome or inconvenient. And then texting, which facilitated yet faster, and more mobile, messaging. These inventions were not created to be improvements upon face-to-face communication, but a declension of acceptable, if diminished, substitutes for it.But then a funny thing happened: We began to prefer the diminished substitutes."-Jonathan Safran Foer.
