“The arrival of the smartphone has radically changed every aspect of teenagers’ lives, from the nature of their social interactions to their mental health. These changes have affected young people in every corner of the nation and in every type of household. The trends appear among teens poor and rich; of every ethnic background; in cities, suburbs, and small towns. Where there are cell towers, there are teens living their lives on their smartphone.” None of that will come as much of a shock. But what’s more surprising (and a lot more worrisome) is the impact that the smartphone era might be having on the social and psychological lives of young people: Less time spent out with friends, less dating, less sex, in no rush to drive, less sleep, more loneliness, and “the more time teens spend looking at screens, the more likely they are to report symptoms of depression.” Jean M. Twenge in The Atlantic: Have Smartphones Destroyed a Generation? On one hand, that title is a little over the top. On the other hand, when was the last time you thought to yourself, “I wish my kids would spend more time on their phones.”
