For me the most important aspects of terminal commands is that (1) you are forced to learn how your OS really works and (2) the terminal will always be able to do things that your GUI isn't programmed to do.
For example, I use brew commands to install brew packages on bazzite because there is no GUI frontend available. I also use it to start ollama LLMs on my machine even though there is a GUI frontend available, because I don't need a frontend for two commands.
I'm not drinking today! I've been sober for a while, and it's getting easier to resist the temptation with time. I sleep so much better, and a nice cold non-alcoholic beer often helps me as a placebo.
