Like playing an instrument or learning a language, learning Vim/Emacs is something you're glad younger-you did because now you certainly couldn't be bothered.

Then again, these days I just use whatever vim-mode solution there is in VSCode, IntelliJ, etc. and move on. Kind of like how I prefer a GUI for Git these days.

It would blow the mind of my younger self. I just have so many other things going on in my life and on my plate.
