Or you're a contractor who has to work on a variety of systems which may or may not have or allow you to install your favourite text editor of the week. It's the lowest common denominator.

(I started on emacs but vi/vim has been installed everywhere and life is simpler when you don't have to faff about.)

Few editors can handle massive code bases like at Google. Google also does not allow coders to store any of their code on their laptop so you have to work over ssh, which a lot of editors don't support well either. I used to use Sublime exclusively but was pretty much forced to switch to vim.

Actually, Vim doesn't change that much throughout the time, so once you're acquainted with it, you no longer need to learn constantly. So yes, there is point.
