No
I've been using emacs for years, I'm a convert from VIM, and I love it to bits.
But any productivity gains from having a better, programmable editor will be totally wiped out by the enormous amount of head-fucking that it takes to get the hang of emacs. It was designed as a console editor, and its idea of interface is not yours.
And even when you've got it completely, your extra productivity will mainly be expressed in the extra emacs lisp you can write.
Who cares? It's great fun, and lisp is the dogs! If you want to 'get things done', then forget about programming. You can always hire programmers to 'do' 'things'.
The only circumstance under which I'd recommend learning emacs for productivity reasons is if you're a lisp/scheme/clojure programmer. It makes such a good lisp environment that then the few seconds it will save you every time you want to do anything will quickly add up to a real gain. And elisp (which stands in relation to lisp as excel macros stand to ALGOL) will seem much less alien if you already use a real lisp.
If you do give it a try, use it on a virtual console where it feels more like a sane way to arrange an editor. Only when that makes sense try to use it under a window system, which will fight with it.
