High achieving adult with a private school education here.
Spent loads of time on screens. Even as a child, I was a massive introvert and had zero interest in sports. It's not as if my parents didn't encourage me to do other stuff - I just didn't want to. Children, much like adults, are individuals who like different things.
I can give you plenty of examples of people I went to school with who did and didn't spend loads of time on screens and did and didn't do well for themselves. Whether kids like spending time playing with tech is to do with their interests and personalities - it's not an indication of anything other than that.
This is propaganda by people with an agenda. Look at the source of that article. Obviously they want to support their own parenting decisions.
They can raise their kids with as little screen time as they like, but they shouldn't make anyone feel bad if their children happen to like technology.
