I feel that it’s less about the screen and more about what you’re doing with it. When my children stare at screens, it usually to play an educational game. When I stare at screens, most of it is work or adulting. About 2-3 hours/week is gaming and 4-6 hours/week is watching some silly show with my wife.

Now, kids in school are obviously doing educational stuff on their tablets so I see the fallacy in this line of thought. Idk. I feel like staring at a book is better, but what do I know? Maybe the increased engagement from a tablet is worth the downsides?
