Another Emacs user here. The article is bullshit. If you use Sublime Text now, in a few years you will be using another editor (Atom?) and so on, or you'll become a dinosaur stuck with an outdated OS just because you need your favorite editor (similar to how some people still cling to WordPerfect running on DOS). On the other hand, Emacs and Vim are eternal: once you learn them, you're set for life, and you'll only get better at using them as the time goes on.
