Same idea for GUIs/terminal, it has a higher learning curve but if you try to avoid the curve you’ll never be able to do it fast, so the time investment is worth it if you’re going to be doing this daily (like most server admins do)
Yeah, part of the thinking behind this question was with those doing this more as a hobby in mind (e.g. self-hosters) where it’s sort of a limbo. You may be doing it daily as part of your hobby, but also never on the level that really demands the degree of proficiency or efficiency you describe as you’re not going to be casually handling a large network of servers (probably), so on one hand learning the CLI may simply be part of the fun, but on the other, it may also lean into overkill depending on what you’re aiming to do.
