Honestly the panic around "screens" remind me of the moral panics around Dungeons and Dragon back in the 80s [0] and video games in the 90s and 00s. The media hysteria did try to blame many acts of violence on DOOM.
Some researchers have now spent 30 years trying to prove a link between violence and video games, without any success. To put things in perspective, during the same time period neural networks were completely abandoned by AI researchers, before coming back and giving us the deep learning revolution and the leaps in self-driving and language models.

In 2018 "obesity prevalence was [...] 21.2% among 12- to 19-year-olds." [1] according to the CDC. That's one out of 5 being obese, not just overweight. And it has more than tripled since the 70's [2]. I have to wonder if it's related. A lot of teenagers are bombarded with images of perfectly healthy bodies that, quite simply, won't match what they see in the mirror. The solution? Ban mirrors.

Your point is valid that today’s smart-phone-social-media is as young as cigarettes were in the 1920’s, but the general problems have been around forever. Young folks comparing themselves to Instagram models is very analogous to air-brushed magazine models in the early 2000’s to cite a recent example. They’ve just been magnified. Smoking introduced a new problem.
