Yeah, this guy is clueless. I could do a point-by-point on how he's wrong, but I don't have time to nitpick everything. What about this: Emacs users need to evolve? To what?

There is nothing else like emacs. Sure emacs lisp could use some help (some of us are working on adding coroutines for parallelism), but that doesn't mean it's dead. If anything else were like emacs but better, we would all ditch it.

Summary: this guy is fucking clueless. He's an IDE-wielding weenie that has only ever used Java. Great.
