Lol terminal is better for everything except maybe the one case you mentioned: first time use feature discovery, and that's debatable

That seems a little harsh. GUI tools can give us a more vibrant and useful interface.

But, I think the main problem is that although there have been many attempts we have not gotten to a standard way to compose different GUI tools easily or repeat actions.

I spend half or more of my time debugging and I think I would quit if I were forced to only use terminal based tools.
