It seems like no one cared that when we got powerful supercomputers that fit in our pockets, we couldn't use them like real computers.
These arbitrary limitations are the real problem. I don't think adding to the collective fear of children using computers will help change that. It's more likely to convince parents to choose more control and censorship.
Taking them to the museum is a exercise in frustration when you find that they ignore any chance to play with the dinosaur bones or look at the solar system models. Present them with a screen and they are captured. I was shocked to see them staring at a monitor that had a scrolling error message on it.. I don't think they are brain damaged, but you would not know it to see them anyware near a tv or monitor. It seems that they have little ability to process the world if it is not presented on a screen.
That's a very related problem.
I spent very significant time during my childhood using computers. At the time, I would have had scarcely anything to prove that time was in any way "useful". I would have been hard pressed to convince others that my behavior was not detrimental.
Because I did spend so much time freely using computers, I learned how to use them. I learned about Linux, partitioning, bootloaders, programming, 3D modeling, etc.
My childhood learning experience happened over the course of more than a decade. It was full of totally pointless endeavors, a very significant part of it was just paying video games (which evolved into modding video games years later), and none of it would have happened with overbearing parents obsessed with the merits of my interests.
