Teenagers have always felt a need to connect with others. Social media allows you to think you are fulfilling it without actually engaging with other people. When I was that age, I had to get up and go out. And I spent time with lots of other teenagers, which also taught me to figure out who I liked and didn't, what I liked to do, and what I did not. FWIW, when my grandpa was that age, living on a farm, he'd hitchhike across Nebraska to meet other teenagers. Every generation has its own version of what they did to meet other kids their age.

That is my real concern - nobody lives a perfect life or is perfectly happy as a teenager. But you take action to find a better life, and grow in those years, on multiple levels, and come out of it having developed into the person you will really be. So who will these kids be who spent those formative years staring at devices? I really don't know... is it just a new flavor of the same growth, or will it be different?
