There’s definitely a fine line between having to learn the ins and outs of something to use it in any capacity and being able to just pick up something and have it work.
Musical instruments take years of practice. But after just a couple weeks most people can start fiddling around. Once there’s a foundation, it gets built on.
Realistically, how many Linux users have memorized every command they use? How many of them actively are looking up lists or guides on how? The memes of developers just being professionals at search engines exists for a reason, no? That’s not to say that there’s no foundation under Linux, but it’s much less encompassing.
Then there’s the whole thing of inconsistency. In music or art, most of what you learn translates. Sure, if you’re a baritone moving to a tenor you might have some adjustments, but it’s quite literally a simple shift. Not the case for computers though, because there’s no transposing from one “language” to another. If you’re following a guide online and you don’t have the same distro, chances are high it will not work.
I’m all for people learning and honing skills to accomplish a goal. I’m also for simplicity and ease of access. If someone wants to set up a personal home server, it does seem a little ridiculous to have to learn the entirety of the ins and outs of networking just because I want to host some local services. Especially when there are hundreds of guides all detailing how to, each with a different way of doing the same thing, and each not working on your personal system for whatever reason. It’s also especially hard when a portion of the community becomes condescending when questions are asked.
All in all I think it comes down to the intent of the tool. For music and art the intent is both to create and to practice the skill for that creation. For computers, well there are people who can practice the skill of ____, but there is also how the computer was marketed to be used by everyone.You have people making the computers and the software and you have the people using them, the overlap between the two has always been small. The idea of practicing computer skills has effectively died outside of programming, which is understandable given that colloquial “computer skills” can now encompass any hobby under the sun.
