I don't consider emacs successful. Succesful among fanatics, maybe, but I don't consider is valuable to a serious programmer. Also, surely it's not that hard to switch languages? In my experience all languages are essentially the same.
Not useful to serious programmers? Do you feel the same way about Vim? Just because you haven't gotten used to using something, doesn't mean it's necessarily total shit. There is a reason why people have been using emacs for decades.
You don't really want to implement all of that in VIM because your work won't be portable.
