The anti-screen sentiment today is like the anti-dungeons and dragons hysteria of the 80s. Back then, D&D would turn your kids into occultists. Today, “screens” will turn your kids into mindless zombies. Some things don’t change.
This generation of parents were pretty much all gamers, D&Ders, and so on. It's not for a lack of understanding. I even play many of the same games as my son and even try to get involved in the ones that don't really appeal to me.
But there is something off about kids right now is affecting them in disturbing ways (to a parent). The change is also been really rapid; it was different even 10 years ago.
It seems to me like a large number of parents seem to be struggling with it.
