When I entered a technical University in Spain, all the masters(teachers that have done incredible things on their lives) used either Vim or Emacs.
Most "normal" people just used other "more visual" editors.
As I learned from the masters I started using more and more both vim for unix tasks and programming and emacs for lisp. Now I use 65%vim, 30% emacs, 5% other editors.
Both of those editors are extremely powerful. But you need to know how to use them. It is not painful for the master to use them, in fact it is automatic and instantaneous and faster than any other editor, a thought becomes an action without conscious intervention, like you thing in playing Do minor in an instrument and your fingers do it automatically, you want to erase a line or replace a word, you think on it, is done.
They are like musical instruments. You could have the best piano or violin in the world, if a mediocre player plays them, you get bad sound.
Most people would be better served with a simple electronic piano or a tablet with lights that point to the next notes of the song, and auto correct them when they play a bad note.
