Regarding “just fine” - I may be mistaken, but my impression is the pre-home PC (and game consoles) generation is more socially adept.
I'm born '86, regular access to technology since the early nineties. I'm a social kind of person, have many friends. Sometimes I just want to lock myself in for an entire weekend and play video games for 16 hours a day. Other times, I'll be having barbecues or going dancing.
And as many here have already stated, the extremes go smoothed over by time.
