Vim is a whole different thing. The popularity of vim is mostly the popularity of the vim way of editing text, regardless of environment. Emacs, on the other hand, is popular as an environment. Vim, or something with "vim" in its name, will remain popular as long as keyboards remain popular. Emacs can only live as long as the intersection of the set of people who are enthusiastic about natively-extensible editing/development environments and the set of people who are enthusiastic about lisp. It's not going to live on as a set of keybinds, that's for sure.
