Hard disagree. Many passions and interests take time to develop, and a big way they (used to, at least) develop naturally is through boredom. I remember well when I was a kid in the 80s who would get bored with my friends in the summer, and so we'd go and build forts or explore (illegally I guess) houses that were still under construction. A lot has been written about "the death of boredom" because smartphones are always there to give you that little dopamine fix to keep boredom at bay.
I agree with the general thrust of your post (technology is pretty unavoidable, and I've never seen a case where parents have been successful "hiding their kids from the real world" past a certain age), but I do think technology has had a severe negative impact on the mental development of youths since the advent of the smartphone, similar to how modern diets have had a severe negative impact to the development of their bodies.
