I'd probably be the same if it wasn't for video games. Wanting to build my own PC was what educated me the most about computers and how they work and learning basic desktop usage. Especially getting into Skyrim and Minecraft mods. There whether someone wants to or not they will have to know basic folder structure and where things are saved and located.

But, without a self driven reason to dive further beyond mobile devices it doesn't seem like schools are teaching people computer basics anymore. So not something learned by everyone by just every day life.

There's always going to be exceptions among those with a more natural tech based interest, but it used to be that everyone was exposed to using a desktop and not something that someone had to individually go out of their way to learn.

This article all day way from back in 2021 showed professors having to rethink how to teach the basics, since now skills that were expected to be known were starting to not be common knowledge.

Gradually, Garland came to the same realization that many of her fellow educators have reached in the past four years: the concept of file folders and directories, essential to previous generations’ understanding of computers, is gibberish to many modern students.

So yeah people who are more interested in PC gaming, streaming, and even pirating are more likely to find resources to be self taught. But, the regular people who are increasingly growing up only using phones as their computing device aren't doing the same until forced to.
