I need to thank Clarissa for spotting this piece in The Atlantic.
The simple argument in this article is that parents are letting mobile devices take away from paying attention to their children. That distraction is retarding development of language and other skills.
One implication is that the leaders in the next generation will come from parents who aren’t connected online or who know how to control their online involvement.
Another possible implication for the US specifically will be in the rise of immigrant children as leaders. The hypothesis is that some/many immigrant parents are less likely to be technology addicts than are parents who themselves grew up with technology in the US.
However, distracted parenting may be a coming thing in other countries as well.
If the hypothesis is true, we’re already into the second generation of children in the US who have been harmed by parental technology addiction.
