I just finished reading Jonathan Haidt’s “The Anxious Generation: How the Great Rewiring of Childhood Caused an Epidemic of Mental Illness.” It is a good read, especially for parents.
I think there's a lot that's wrong with phones, but I can't help but think of scares from decades past that were laser-focused on inducing parental panic, but turned out not to be as harmful as initially reported: the fears of Rock 'n Roll making teenagers out-of-control lascivious horndogs, the Satanic panic, DARE/war on drugs, etc.
