I'm a high school teacher, so focusing on a younger age group that your demographic, but they absolutely don't teach kids these things. The only class we have with a computer is a typing class that lasts 12 weeks where they essentially play games online (the teacher is also a nutjob; anti-vaxer and flat-earther!)
These kids type their entire papers on their phones and save it via Google Drive. It's not surprising they really don't know how to do anything with computers.
Millenial here, and because I spend pretty much all my time on my phone when I'm not programming, I sort of feel a bit like a gen z'er.
I do a number of things on my phone that would be faster and 'easier' to do on my mac, but which I don't simply because doing it on my phone is more comfortable/natural.
Yeah, it's weird. However, my phone has become a part of me (in a way). Doing things without it feels unnatural.
Being able to sufficiently handle technology can be a matter of learning a trick and sticking with it. A difference in mentality or 'skills' is the ability and curiosity to learn new tricks when a situation calls for it. So it's not really a generational issue (now that I think about it, generational issues are not really related to the 'quality' of the people in it, but the environment that shaped them - heh), it's a mentality/skill issue. The will to actually solve the problem in front of you is a skill that can be learned, but if everything around you 'just works' you never have the need to develop that skill.
You've been happily using your Generic XPad your entire life dealing with minor UI changes that are explained to you via small tutorials or w/e. You learn your job on the job, specific things in school etc. The furthest you'll go is the search bar on Facebook or a marketplace.
If you encounter something that doesn't just work, how do you know how to figure it out if you've never developed that skill. To me and you it's not that hard, it's pretty obvious.
People just learn the trick, but not how to be curious. Or maybe they just don't care, that's fine too I guess.
