I take great care with my VSCode extensions and their configuration. I likewise take great care with neovim and having it set up properly.
Modern Emacs Lisp is easily the best environment among my daily drivers for interacting with my editor in real time.
Of anything modern I only know Zed a little: Zed in theory might be better than Emacs.
Outside of maybe Zed, which I haven’t mastered, Emacs Lisp is bar nothing the best tool-making tool for serious hackers.
