Currently a med student, and interestingly, some of the most renowned researchers in the world, not surprisingly, use Word. I know it strays from most of the users' fields of interest/research, but this is pretty funny, at least in my head..

For most people, LaTeX is pretty funny. Most disciplines did not use LaTeX. I'm sure there are plenty of big journals that never supported it. LaTeX became en vogue mostly in disciplines that involve a lot of math. Even in economics, a lot of journals were always majority Word.
