You know neovim can use the exact same LSPs (Language Server Protocol) for intellisense as VS Code right? There's intellisense, git integration, code-aware navigation, etc. Neovim can be everything VS code is (they're both just text editors with plugins), except Neovim can be configured down to each navigation key so it's possible to be way more efficient in Neovim. It's also faster and more memory ~~edficient~~ efficient because it isn't a text editor built on top of a whole browser engine like VS Code is.

I use a Neovim setup at home (I haven't figured out how to use debugger plugins with Neovim and the backend I work on is big enough that print debugging endpoints would drive me insane) and I can assure you I have never given variable names one letter unless I'm dealing with coordinates (x, y, z) or loops (i, j) and usually in the latter scenario I'll rename the variable to something that makes more sense. Also, we don't do it to seem hardcore, it's because there are actual developer efficiency benefits to it like the ones I listed above.

By your own logic you "can't be bothered" to learn how to edit a single config file on a text editor that has existed in some form for almost 50 years (vi). Stop making strawman arguments.
