For what it's worth, I learned Emacs out of my desire to learn Clojure. It didn't take too long to develop the muscle memory (a few months of forcing myself to use it). Now, 6 or so years later, I use Emacs for essentially all ad-hoc text editing jobs, and of course Clojure dev. I love using it for my shell (M-x shell) - being able to move about the shell buffer w/out limit is very liberating.

I also do a lot of iOS development, and, I do 95% of editing in Xcode, and 5% in Emacs. A nice thing about Emacs is, if you're on a Mac, is that Mac OS uses most of Emacs' movement keybindings, so even when I'm in Xcode (or any other app for that matter), I can still use my Emacs muscle memory.

I'm not that young; 6 years ago I was 30, and I'm very happy I decided to learn Emacs; no regrets. It's still paying dividends today and will continue to for the foreseeable future.
