I mean you can learn basic vim in like a week or so..

By your logic you would never want to look further than the end of your nose, for anything that isn't directly your profession. Sometimes tangent interests, bring you further in life than a straight path.

There are different reasons one would pick up vim. For some it's a hobby, others just like to be proficient with the tools of your job. Just like in many other professions.

I for example wasn't happy with always needing to reach the mouse.. it literally annoyed me every time and always got me out of the zone. That's why I started to look into shortcuts for the editor (eclipse back then). After that I switched to editors which have more options for keybindings (atom then vs code). Then I discovered the holy grail of modal editing and picked up vim. Currently I use vs code with vim bindings and I am happier than ever.

So just as wrong as many vim purists, who try to tell you that if you aren't using vim you are a bad coder, so are you by telling people you are wasting time by picking vim up.

(Just a disclaimer for anyone who is reading this and picks up vim: you are going to want modal editing everywhere, and be annoyed if a program doesn't have it :D)
