We were talking about normal user stuff that normal users do, not “seriously advanced stuff”… And I agree that most normal users probably don’t want to use terminals because they are not familiar with them. But normal users probably don’t and shouldn’t do “seriously advanced stuff”, no?

Yes, if you are trying to do “serously advanced stuff” (whatever that means), chances are you will probably need a terminal (or a terminal will at least be easier), but you shouldn’t be doing “seriously advanced stuff” unless you know what you are doing anyway…

Unless you have a system without a GUI, you don’t need to open a terminal in order to update or install stuff. There is a GUI for that. And no, you don’t need to build stuff from GitHub for normal user stuff…
