Yeah, there is some truth to your D&D scaremongering analogy, tho I don't think anyone is calling for parents to lock arms and drive Satan out of the Apple Store.

I think there is a big difference in the devices and content of yesteryear and the magic phones filled with an unlimited library of today. Eventually the cartoons would end and we would emerge bleary-eyed into the daylight.

I wouldn't be surprised if there is a quantitative difference in the life outcomes between kids who were given firm boundaries by their parents and kids whose parents just gave up and let them watch any old shit. We are running this experiment on live humans, so time will tell.
