Oh, it's a real flamewar and people still seem to be here, so I want to add a little constructiveness to it. Vim, bash, LaTeX. Let's postpone vim, as the whole topic is [supposed to be] about it. And we have enough shells (zsh, fish) instead of bash, many people (me too) tried it and have chosen bash (although I use IPython quite often). And I don't know sane and fully functional alternative to LaTeX. (Markdown and co don't count as they don't have same control on output.) So let's stick with LaTeX. There are 2 categories of people: those who think that LaTeX is fine for its usecases and those who think that something is wrong and could be done better. Fine is fine, so lets concentrate on the second category. I'll recite main complaints: slowness, horrible syntax, arcane source code, impossibility to divide semantics from representation. (Did I miss something?) I guess many of us are able to program. So why somebody, right here, right now, wouldn't create a github/bitbucket repo, post link on it and explain, what exactly in your opinion could be done better? I personally would probably participate if somebody has a plan sane and explicit enough.
