I wish I had the enthusiasm, grit and dare I say "sisu" that lisp developers possess. I worked with a guy - very skilled Clojure developer - who was an absolute wizard in Emacs. If a car company sold a vehicle that was powered by emacs, he would have bought it. He will probably construct his own casket out of elisp to be buried in.

Emacs was not originally written in Lisp and is a great programmer's (and general) editor even if you never touch or think of Lisp. You can even write (and save and edit) keyboard macros knowing no programming at all.

Didn't emacs give Stallman RSI? No thank you, I'll still with vim.

If you already know Vim, you should probably not use Emacs without Evil:

It gives you comprehensive Vim bindings so what you need to learn to be comfortable in Emacs is very little. As a bonus, it also keeps your RSI risk unchanged.
