I think this sort of hyperbole is unhelpful. What people are worried about is more mundane: whether the hyperconnectedness will make their kids less happy in the short or long run. There is some evidence that the age of first smartphone negatively correlates with these outcomes. [1] For my daughters, I worry about social media use, body image issues, and the like.
> Just delaying their first contact to the age of 13/14 won't magically guarantee they will be able to navigate it responsibly. This is just magical thinking born out of laziness.
I don't think most parents think this would be a magic bullet. They just think that it is one (important) tool in the toolkit. We understand that parents (noun) are supposed to parent (verb). It's not lazy to say that we think our children would be better served if their brains were a bit more developed before they are confronted with the world of addictive apps and always-on social media.
I'm glad to hear that things have worked out well for your kid. There are of course a variety of outcomes for different kinds of kids. No one knows whether their kid would have been happier (or would have grown into a happier adult) had they done something differently. We are all just trying to figure out how to do our best, and for some people that means slowing down the rate of change from one generation to the next.
