I mean, if you're too conservative to use modern technology, this doesn't seem like the right field to work in.
That said, the vim guys do seem to get good work done somehow...
That's just flamebait.
I like vim and Emacs. There are good reasons to use either of them (or e.g. their bindings in "superior" tools).
Still, the quoted "must use vim/Emacs!" is just stupid. The point is that the work needs to get done.
That kind of attitude ("why aren't you using <insert personal preference bloated point-clicky IDE released 6 months ago>?") is just as obnoxious as what is in the article.
I wish people hated me for what I actually say, not what they imagine my attitude is :)
