My first editor was the RT-11 editor, which some sadist at my first job ported to the Perkin-elmer machines I worked on. Then TECO, which the same sadist also ported (but it beat snot out of RT-11 editor).
Then vi.
Then something, anything else other than vi. vi makes TECO look good!. 'bout that time, PCs started happening, and along with them came word processors and real visual editors. vi became the anachronism it is today....
