I'm not sure this assumption holds true enough: incredible numbers of humans have already substituted vast swaths of direct human-to-human contact with the gigantic text-only condoms provided by the internet. We've already traded in superior quality human contact for inferior quality contact--for the bonus of more specialized content which we probably wouldn't get if we knocked on our neighbors' doors.
This doesn't necessarily invalidate many of the proposals in this article. But what about the dimensions in which AI provides or will eventually provide a superior substitute to human-to-human contact?
