Earlier quoted context omitted.
"Nothing I learnt in high school required anything more than pen and paper." does not make exception for class about computers. And to add to it, those who had access to computer only in class were super behind those who had free access to it.
You keep misinterpreting what I have said. Nowhere I have written that I didn't have access to a computer at home or that kids should not have a private computer. I really don't understand why you keep hammering this point.
In that setup, learning about computers basics is limited to people whose parents are proactive with it. A kid whose parents think no screens or no screens except for school is out of luck. A kid whose parents allow computer but don't teach anything useful on it is out of luck too.
Both elementary and high schools should and do teach those things. I don't know how they are supposed to teach that without school related access to computer.
