Something I often need to keep in mind is that when I was growing up the home PC was pretty crude and mysterious. You had to learn what a command line was, you had to learn about data backups and file trees, you had to learn about navigation and discovery of the web.

Sure you might not have done any of this stuff for decades now, depending on how you engage with the infernal devices, but if you see a forum you know what that is, how it works, what you expect to find inside. If you see URLs with like foo.com/place@otherfoo you kinda intuitively grasp what that is saying.

But if you're like 20 now probably the first computer you ever touched was a magic box where you just clicked things to open stuff and they managed their own little things. Clicked a thing to install other clicky things. You don't know what a config file is, why would you? you don't really use URLs much, you just click the internet and start typing and then click the right link etc.

To a lot of those people some of this stuff is as arcane as like arch linux is to your average millennial PC user. Despite fedi (and arch! I use arch btw) actually being really simple and obvious there's a barrier of unfamiliarity and a lot of basic skills you need to learn first.
