This is exactly what I think about the story. Smartphones are now part of our lives, the only solution would be a global school banning of phones, but it isn't practical.

If you want to give your kid as a present a bad life experience, don't buy a phone, but then live like a person in a cave, while the world goes on.

The real lesson is to be a good parent and define clear screening times, at least at home, where you can, more or less, control it. But a total ban isn't possible IMHO
