There's an interesting book I read recently related to this called The Anxious Generation: how the Great Rewiring of Childhood is Causing an Epidemic of Mental Illness. I'd recommend it.
I'm so mixed on that book. Lot of great info in it, some good thoughts on child development. But soooo much moral panic under the guise of science. The data used is fundamentally unable to establish a causal link.
Yes putting real life focus on children and relationships is a great thing for child development. So I guess a book furthering a moral panic to do so, while purporting to be above moral panic isn't fundamentally evil.
I'm worried it helps create a boogeyman, though, and the children it seeks to help are being harmed by the backdrop of the existential crises of our time like global warming, the authoritarian wave, etc, and social media / phones is just the most convenient vector through which this all flows.
