Youtube is turning 14 next year and computers have been mainstream way longer than that. Personally I was a kid when it was the TVs fault and video games were making kids violent, but imo things turned out just fine.
Cue Monty Python sketch
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.
