The only way to learn Linux is a little at a time.. unless you are studying as a system administrator.

I'd say as far as liking terminal or gui that they really solve different jobs. The terminal is just another application, like excel. It's like asking if you prefer Word or Photoshop. You'll start to like the terminal as you start to find use cases for it. If you had never seen excel before and were exposed to it, it would be reasonable to say, "So you can write numbers in a grid? I guess that's useful. And what's this complicated formula business?" You probably wouldn't go in it much not only because it would be unfamiliar and painful to use, but you wouldn't see much benefit if you've spent your life applying zero usecases to it (because before you were forced to have zero use cases for it, or really because windows-CMD is a 90% useless terminal).

I suppose with installing software that could be made a shell command or gui, and that's likely what you are doing a lot of right now. But one cool thing is if you need to ask AI something, if it was for a gui you would end up with long descriptive instructions to read through. And if it is the terminal, you can just copy and paste. The second one takes about 0.5 seconds of effort. It seems annoying that the content seems unintellegable if you don't know what the code means but you just teleported through a mountain where with a gui you would have to walk over it. Maybe if the gui is made well the jouney over the mountain is visually plesent. But you can never copy paste menu clicks into a gui from the internet.

But I say don't use the terminal if you don't enjoy it. Use the applications you enjoy using. You'll also enjoy it more when you can make simple programs. Like the super simple one I made yesterday:

#!/bin/bash

cd ~/.local/share/dsda-doom
dsda-doom Doom2.wad BB2025_RC5.wad BB2025_alt_music.wad

Now if I want to launch that exact map set in doom I just type bluesbrothers. I don't have to select each of the exact wads in a gui before playing. The terminal removes repeditive actions because you can script them away.

Just open a few programs, use the system for some time. Try upgrading your system, perhaps. Before long it will crash.

You like the terminal when you want something you can type in exactly, repeatedly, and write down, rather than looking up outdated video instructions that show dialog box options that no longer exist in the version of the software you're using.

Also if you re-use commands a lot you can just turn them into shell scripts and make em executable. AI can cough up the magic incantations pretty easily these days.
