Find the skills gaps that you have; find the thing that interests you about it; and dig into that fundamental piece, don’t understand what the fundamentals might be, go check out .edu, or certification outlines with the vocabulary/knowledge you do have so you can build from the concepts (and benefit from their already determined progressions) , so you can developed additional vocabulary and knowledge of the discipline.
I think the gatekeeping part isn’t the warning or cautionary advice being given, It’s the failure to point, and give direction to, the relevant thing(s), the skill sets, the place to start in order to understand the complexities.
Like the hart-surgeon analogy given elsewhere in the comments; it’s not just the dire warning of ‘you can kill someone’ - it’s the humanity to say, well if you want to learn how to do this, you’re going to have to start by having an understanding of basic biology, organic chemistry, human anatomy, etc, and to learn about those things go here…
I think you’ve missed the point OP is trying to communicate. It’s not that these things aren’t relevant, highly important, and good caution/warning. It’s the gate that people are creating with these no depth explainers. “you need to understand” “if you don’t know” – then fail to provide direction to people who want to know, to learn these things, to figure out where to start; that’s the gate.
Also, I’ll add, that I think that beginners learning this immutable, devcontainer, distrobox workflow offers you more space to practice and learn by doing. You’ll will learn a lot by recovering from some misstep (rollback), and/or by blowing it up, to rebuild it again. (and I encourage you to do it often for the practice and confidence)
Check out the ‘dx’ variants within universal blue It would be a good time to become familiar with rebasing.
I run bluefin-dx environment. (gnome).
There is a different learning curve to immutable/atomic systems and workflows. I don’t think it’s harder per say, it’s just you’ll have to be cognizant of the differences when searching for relative and relevant information when you come up against anything (like any opinionated *nix distro). Learn Homebrew, and Flatpack (and thier quarks running with atomic systems).
