Yeah, growing up in the 80s or 90s might have had you uniquely well-positioned to be "good with computers", because "the computer that has games and the internet" was (in some sense) the same as "the computer that adults are supposed to use for work".

That's not true anymore in the smart phone / tablet era.

5-10 years ago my wife had a gig working with college kids and back then they were already unable to forward e-mails and didn't really understand the concept of "files" on a computer. They just sent screenshots and sometimes just lost (like, almost literally) some document they had been working on because they couldn't figure out how to open it back up. I can't imagine it has improved.
