If you ask someone if they heard of Emacs they will probably say; “Yeah, I remembered it when people used it long time ago”. But most people will look at you with a bushy thing going on in their face.
My first experience with Emacs was when I studied. The teachers wrote lab-instructions: “Open your favorite editor and follow the instructions. We will assume that you choose Emacs. If you didn’t choose Emacs, good luck, your on your own!
