The problems mentioned are huge in the over-30, non-tech crowd. I worked IT in college, and the skills of professors and admins older than 35 were much worse than the average English major in a computer lab.

They viewed the machine as a Magic Box that let them type documents and browse the web and sometimes crashed if they angered it. Some needed help getting CDs out of the tray. Some didn't know that "check if it is plugged in" is a troubleshooting step. Some were very superstitious about crashes ("don't move the monitor!" was my favorite).

If you don't see anyone struggling with these concepts, well, I haven't since I got a programming job 3 years ago. They didn't stop having problems, I just don't see the problems anymore. Always watch out for selection bias: the set of "people you know" isn't representative of the population at large
