I vividly remember witnessing what Sherry Turkle describes as being "alone together" in her book, Alone Together: Why We Expect More From Technology and Less From Each Other (2011). I was in Seattle on business sitting in a restaurant. At the table next to me, six or seven twenty-somethings all had their heads pointed toward their laps, tapping at their smartphones rather than interacting with one another, as they waited for their food to be served. Not healthy.
