I would note that friendship has never been defined by the casual and vapid interactions at the grocery store. My longest lasting friendships have been ones I formed on irc 30 years ago and still go on, despite only rarely speaking face to face.
People who don’t understand something that didn’t exist when they grew up assume it must not be possible. People assume that games crush creativity, that social interaction online is not actually social interaction. These same biases based on “the way we did it” show up in the RTO debate and other areas of society that are being changed with a new mode of interactions.
Human beings are remarkably adaptable, and I don’t think for one second that online interactions are necessarily worse. I do think we are going through a transient period where as a society we adjust, and transient periods are rough. But as we learn to exist with these new modes of living we, as a social whole, will simply adapt how we interact and live, create new social rules about how to best exist with these new tools.
As we did with language, written words, books, newspapers, telegraphs, radio, telephones, television, etc. Every one of these was greeted with fear and disdain, and social disruption as we settled through a period of transformation. This one is no different.
Hand wringing and bans and teeth gnashing will happen, won’t help, and won’t alter the course of a single thing. Better, IMO, to lean into learning how to live with these advances in a healthy way and teach your children that. Banning them from learning the complexities of a new social medium until they’re old enough to get into serious trouble will only hurt your kids.
