linux guis vs the linux terminal:
"here's your broom closet. it's accessible only to you and you can get your tools out with the graphical interface on this simple touchpad"
"what if i want to make the broom closet accessible to someone else on the starship"
"you'd have to go to the bridge and issue the right commands to the permission control deck"
"that seems incredibly dangerous"
"don't worry, the worst you can do with your credentials is destroy every last one of your personal belongings"
"of course those of us who've been on the ship for a while just do everything through the control deck. it's much faster that way. we're space cowboys, wheeee"
