There was a post here a while back about how younger generations often don't understand concepts like file system structures because concepts like that (which are still relevant in a lot of contexts) have been largely stripped out of modern user interfaces. If your primary computing device is a cell phone, a task like "make a nested directory structure and move this file to the deepest part of it" is a foreign concept.

I guess my point here is that I agree with yours about this being cyclical in a sense. I feel crippled on a cell phone, but I'm also in my comfort zone on a Linux terminal. Using web apps like MS Teams is often difficult for me because their UIs are not things I'm comfortable with. I don't tend to like default layouts and also tend to use advanced features which are usually hidden away behind a few menus. Tools built to meet my needs specifically would largely not meet the needs of most users. A Level 1 user would probably have a better experience there than a Level 3 like me. It's hard (maybe impossible) to do UX design that satisfies everyone.
