I'm not talking about performance but learning curve and unnecessary features. I don't really want to learn any key bindings or a whole new ecosystem just for a text editor I use to edit a config once a month.
I used Doom for a while, but it was still slow. I’ve been replacing emacs with more unix-y tools (helix/neovim as editor, yazi for file manager, etc.). I really just miss the design of emacs (the self-documentation, the infinite extensibility, etc.). I hope someday maybe Lem will fill my needs (which I just learned about yesterday).
