However, seeing my own kids' behavior even when I heavily restrict their screen time makes me question that. When their time is up they wail and moan and yell in a way that goes well beyond the usual kind of complaining kids do. I tightly control the apps that my kids are allowed to use and limit their time (thanks to iOS screen time). In the times when I've taken away iPads as punishment for extended periods, my kids' moods have improved. The amount of arguing has gone down. Their behavior is better. It's inescapable that these things alter them in some way. This is without social media even!
I genuinely don't know what the right answer is. On one hand, they have this amazing machine that is a gateway to all sorts of learning. It's almost like we've stepped into the world of "Diamond Age". On the other hand, it makes them turn into borderline sociopaths, even when they use it for short periods of time. The addictive effect is real too, and that is also frightening. If given the choice between anything and iPad time, iPad time wins hands-down 100% of the time. The human race has entered a whole new unexplored territory.
