Emacs lacks C programmers. Maybe it is related to how easy it is to get something working on each language. Elisp has a huge advantage over C on that aspect, not only because Elisp is more simple and way more expressive, but also because of the REPL (no edit-compile-run-crash hamster wheel) and because Emacs is, in practice, a Lisp machine with the associated advantages. Elisp is a hacker's dream. Not so C.
