This is from the author of the excellent book Mastering Emacs.

I am very far from being knowledgeable about programming on the Emacs platform, but I am trying to learn. I grabbed the name M-x-AI.com a while back with the goal of integrating other people’s Emacs packages with some of my own hacks into a better AI dev work environment and writing a short book on it. I have been using Emacs since, I think, 1982. There are so many good new packages for integrating CoPilot, GPT-4, etc., as well as major Emacs platform improvements that are too many to list.
