I do not understand why this article has such a negative bias against vim and/or emacs users. Comparing an emacs/vim user and a dog that does not want to walk on grass seems gross. Even calling them stubborn, well... The authors claim that "Modern IDEs are magic". As a freelance devops, i don't code-for-a-living being a magician, all i want to do is editing text, most of the time there's no magic involved.
"Why are so many coders still using a keyboard?" Answer for yourself.
I have been using emacs for a decade, and finally settled on vi/vim because of its broader availability. Both are excellent editors. I have also used dozens of graphical user interfaces for development, but as a devops i sometimes find myself in an environment that does not support graphics.
Not having graphics at your fingertips may sound like a restriction, but it allows me to focus on my code rather than being distracted by color, hints, hovers, help, type ahead, code completion and the like. I do not need all that, i can freely speak my favourite programming language same as i can write a text without referring to the encyclopedia britannica every other word.
Final rant: i consider the bio "He's spend over 15 years as a technical writer" as sloppy as the whole article.
Well, than Python. Who would have thought that?
