Editing text efficiently is not the same as being a productive dev
That's like saying suturing dexterity does not a good surgeon make.
Anything that reduces cognitive friction, including the ease with which
keystrokes go from your brain to the screen, makes you a better dev.
I'd say vim wins the fewest-keystrokes battle. But emacs wins the war
because it leads you to lisp, and lisp makes you a better programmer.
