Exactly, nobody can. When we were drawing in horse crap - a car was a life saver. Now everyone complain it's killing us with cancer and drawing us in the future melted ice caps. Nobody can tell what impact it will have on human brains in 100 years... I deff know that watching cartoons all day is bad. And a lot of parents do just that - here is an iPad, just shut up and let me be. But if it used for study... Who knows?!
