I am terrified about giving smartphones to my kids. France's new rule (no smartphones in schools - no exceptions) is genius, and I applaud them for that. What is a supercomputer in your pocket, with access to a significant portion of the sum total of human knowledge, good for, for most people? Playing fucking candy crush. We wish that we, humans, were better, but we are not. So what can we do about it? I have no idea…
I am terrified by the fact that so many other people don't think twice about handing their toddler a smart device. Every time we go to dinner, there's a table nearby with a tablet planted in front of a child in a booster seat.
"There's no evidence that it's harmful", people say, but how could the evidence possibly exist? It would take 16+ years to do a thorough study (possibly longer), but smartphones have only been popular for half that time. And people have only been using them as babysitters for the past 3-5 years, at most.
We may not know the true extent of their damage until it's far too late for the affected generation. There's always a chance that the damage will be minor and/or reversible, but most people don't seem to grasp the risk they're taking.
