Same - I regularly use vim on servers when I have to, but I can only remember some super basic commands. Most of my coding is done in a basic text editor like Sublime Text or Notepad++ or an IDE.
I do get the appeal of becoming fluent in Vim or emacs and theoretically attaining giant productivity gains. Although for me at least, text editing is not where all my time is wasted. I lose my productivity the old fashioned way: attending unnecessary meetings and wasting time solving the wrong problems.
The tough thing with creative endeavors is that you really just need the motivation to start and continue making anything, it can be inexpensive stuff. The important thing is output and making it a regular thing.
That being said, gearing up for a new hobby is always fun if you can afford it. But you can absolutely make short films on an iPhone.
