I wonder (and maybe vainly wish...) if it will reach the point where it breaks, and a few alpha fe/males just say, Hell no. And it becomes a trend NOT to do it.
I run a 1-year program for young professionals. Three times in the year, we do a camp-out weekend. No phones, no watches, no electronics, no showers, no beds (sleeping bags). They love it. Most have never been without their phone that long. But I look at them huddled around a picnic table, talking, laughing, so PRESENT to one another....
It's possible. We just need some super-strong-willed, gregarious, opinionated examples.
(And yet, here I sit, in front of a screen....)
