This is just the latest fallout from the "digital native" hypothesis that people will learn computers by osmosis and thus don't need to be taught. People don't understand computers? Teach them!
Younger sibling did not, so we end up teaching them. You don't learn how to use computers by osmosis and I'm glad people are pointing it out.
EDIT: I had typing classes too. It's astounding how many younger people I see who do not know how to type properly. I'm not even 30 and I'm already going "back in my day..."
I'm not a teacher, and I didn't go to college. I barely graduated high school.
I just have a passion for being paid far less than anyone around me while doing the most work, I think.
