What a great find. Not sure why I have not discovered Prot before. Bookmarked the article and this thread.
I have been using Emacs for about 40 years, and as a crazy side effect of the mountain of LLMs hype, with a lot of productivity enhancing goodness, I think that Emacs can only gain in popularity because of several excellent Emacs LLMs packages. Most of the world is exploiting LLMs with VSCode and its variants, but Emacs is also just about perfect for integrating LLMs into workflows and for having fun and playing around.
