Preschools definitely brag about having no toys with electronics and the posher the elementary school, the less screen time they have.
At best, it's a mixed bag.
When we visited schools, we were also very surprised at how many schools encourage screen time. One of the most reputed school near us require each child to have an ipad at 6 years old. I'm completely against that. I see no value in introducing an addictive locked down device this early on. Instead, we chose a Montessori school that forbids electronic devices on campus except for the computing room where primary school children can go with a clear objective in mind (research, robotics project).
But, it was really surprising to me that that school is the exception and most highly ranked school have significantly more exposure to screens even at a very young age
On the other hand, these kids will eventually end up in a world saturated with displays and maybe even AR, so there's some argument for getting them involved with digital stuff at some point.
And that's how the argument usually goes, but I don't buy it: every one of us who attended schools without devices learned to pick up that skill some other way. And usually without any problems.
In my opinion, the trade-off swings hard into the wrong direction: there's much more downsides to using devices in the classroom than upsides for the most part.
Everyone? You sure? That has not been my experience at all. (It's also a very bold statement on your part to be speaking for a whole generation of people.)
My experience is that people who are not absolutely raving mad about tech do not, in fact, pick up computer skills on their own. My parents have been struggling with technology their whole lives (even basic things like writing in Word, keeping an email address book or bookmarking websites). I picked up these things as a child but I was also interested in programming and networking and more complex tech things, and it was blindingly obvious to me that this is rare because there was maybe one, at most two other kids like that in my school. Nobody else in class had the faintest conception of what programming is really like.
Even today, while talking to people online as well as offline, I am constantly reminded of this. People do not pick up tech skills, period. That includes people in intellectual fields (math teachers, puzzle enthusiasts, what have you), so it's not a matter of intelligence.
Now, I want to make clear that I'm not saying people need tech skills, or that tech skills should be taught in schools, or that a lack of tech skills is somehow an indication of some sort of lack or decline. I'm actually of the opposite view: I think most things taught to children in schools are useless in later life and I think we are squandering children's talents, curiosity and creativity by trying to force, coerce and mold them. As such, I agree with the sentiment that sitting every child in front of a screen for hours every day is detrimental. I just wanted to clear up this vast misunderstanding that just because you picked up certain skills without being taught, everyone would. It does not work that way. You picked it up because you were interested and passionate about the subject. Not everyone is.
