Right - of course, I don't really know the cultural background, having not been around when those expectations were developing.
None of my classmates learned computer skills by osmosis. Every single one of them that did learn those skills put in intentional effort because they were already interested.
And even so, the schools were entirely stacked against us, intentionally or not. One kid (I still am not sure who) went through the computer lab and tweaked some settings to mess with everyone. Another kid (who definitely was innocent) stepped forward to help fix it, and got suspended for a week or two. Show any kind of competence with computers and you're a dangerous hacker. Fall in line and don't stand out or you will be punished.
