The main reason I like vi/vim is that if you’re having to use multiple different computers (such as if one is a sysadmin, or in my case, does scientific computing), because if you’re running on Linux, you can be confident that vi/vim will be on it.
For personal use, I’ve been using emacs, but I can’t recommend that without feeling like I’m suggesting you try some heroin. I enjoy emacs because of it’s complexity and how much power it gives me to modify it. It’s very easy to fall into feature creep and over complexity though. That’s why I can’t recommend it — it’s good for me because I am a chronic tinkerer, and having something to fuck around with is an outlet for that.
I would recommend learning the basics of vim though. As you highlight, getting back to your current level of productivity would take a while, even if you loved vim and committed to it wholeheartedly. It is possible to try it out with little commitment though, for the perspective. If you’re on a machine that has vim installed already, try the vimtutor command, which will start the ~30 min long inbuilt tutorial for vim. I liked it for giving me perspective on what on earth vim even was.
I know you don’t use it anymore, but I just want to fistbump you re: sublime text. I really loved that as a basic text editor that was, for me, just a slightly nicer notepad.
I’m more likely to have conversations. I tended to lurk pretty deep in threads on Reddit, or on niche hobby communities, but that vibe is much more available here.
There seems to be more good faith discussions here. I see more people apologising, or responding well to being called out. I realise this is largely a function of size of the site, and thus this nice energy is likely fleeting, but I am heartened by it nonetheless; people like us will always exist, and there will always be a place for us (even if we need to make it ourselves).
