From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I didn't say you have to know everything, just like I don't know everything in my house and how it works, but I do know how to do basic repairs so I don't pay loads of money for a guy to come and unclog a drain. I know how to reset my circuit breakers, how to change a fuse, how to change a lightbulb.
That's what the terminal is. No one here is telling you to write a bootloader in assembly or meticulously study kernel environment parameters. No one advocating for basic knowledge of a terminal likely has knowledge on subnet masks, compilers, or other low level systems that a modern Linux abstracts for you.
But! I know how to update my packages from a terminal. I know how to install a package outside of a repository, or one that's not listed on my graphical package manager. I know how to export an environment variable to get my software to work how it should.
That's what "knowing the terminal" gives you. It's a basic skill that unlocks you from being a mere "user" of a system to an owner of a system. I don't think everyone will ever need the terminal, but there are people who are replying to me that seem to have a genuine fear that people have knowledge of their computers in a meaningful way.
Knowledge is autonomy for whatever you do, and there's a reason why the most profitable of systems are the very systems that are locked down abstracted and "user friendly" in all ways that harm a user's rights and freedoms.
I'll coincide with you in that first-aid-quick-repairs is something people should in the best of cases know how to do, but setting a envirental variable or installing a package is not a "simple thing". I've worked with engineers that programmed math models for a living that had no idea what a enviromental varible even was. Yes is easy to do, but the concept behind it, what it is, what it does and why are not simple, without the right background or the will to learn about the topic.
And, about user and owner. Sure, I get your point and personally I share it. But again, that is an opinion, tell a non-interested-user that they don't really own their rig until they know how to use the terminal and I assure you that most of them will disagree.
Edit cause I wrongly posted before finishing: Comparing uncloging -manually pushing and pull a bar- or chaning a light -turn left, change, then right- or a breaker -literally just pulling a tab up- are WAY simpler actions. Yes, running apt upgrade is easy, but how you know is all well? That it work? + if I run apt update everyday I see almost no diference in my system, why should I even do something like that
I think this is the bigger issue, to be honest. Like your example of environmental variables, it's not a complicated concept, but when a guide says to set the variable for Editor rather than a context menu asking you to choose the default program to open this type of file in the future, all of a sudden, people lose their minds about how complicated it is.
These examples don't make sense to me as a point against using the terminal, especially since GUI package managers are a thing these days. Many upgrades are under the hood, so to speak, and don't produce visible changes for most users, and this applies just as much to other operating systems as it does to Linux. When Windows finishes upgrading and reboots, or Chrome tells a user updates are available, and they restart it, how do they know all is good? For the most part, they take it as a given that all is good as long as there's no new, undesired behavior that starts after the upgrade.
Just because I haven't been exploited by a security vulnerability or encountered a particular bug is no reason to remain on a version of my OS or programs that is still liable to either of them. That's just a bizarre argument against staying up to date.
