For me, the reason to learn vim is because if you know how to use it it's a really nice editor that's preinstalled on almost any system you shell into. I use VSCode on my home system and occasionally on a remote system, but I'll use neovim when doing a quick edit from the command line and vi when I happen to be o a remote system. In my ideal world, I would just use one editor everywhere, including if I'm hot-seating on a system that is not mine and without internet access: having vi already under my fingers is a nice approximation of great editor + everywhere.

Yeah but it’s a small island.

If you learn Vim you’ll have access to Vi and Vi-like interfaces in lots of other software including terminals, database clients and everything that uses readline.

Helix is wonderful. I did make one keybinding change: Switching in and out of Insert mode is CTRL-i so I don't have to wander off to the escape key so often.
