Tilable interface, requires days to set it up, tweet with i "Hello World!" <ESC> t, native vim keymap support, and hard to quit.
vim is not GNU, emacs is.
That means it would actually be <M-t> Hello World! <C-x> <C-s>, and the documentation would have a lengthy section on what the "Meta" key is and why not just call it "Alt".
EMACS dates back to 1976 (David Moon & Guy Steele); vi also dates back to 1976 (Bill Joy).
GNU Project dates back "only" to 1983, with GNU Emacs soon after: 1984.
