Not totally related to your point BUT I’d like to tack on that lisps and generally repl-friendly languages are in an interesting spot in the LLM-enabled world.

The calva-backseat-driver vscode extension runs an MCP that lets LLMs manipulate and eval clojure expressions in a REPL. It provides a tighter feedback loop and lets LLMs do much more complicated stuff with much more confidence. They can test functions as they go, read docs, check query outputs, write and eval tests. It’s actually crazy what Claude opus can do with REPL access.

It might be insanity to let an LLM modify your emacs on the fly, but I’m sure people will have some crazy and interesting ideas in that vein!

I don't let it execute emacs lisp itself, but elisp generated in org mode babel blocks which is instantly executable is a fine way to have gptel improve itself.

This is super exciting. Emacs already treats UI as just more Elisp to eval. The AI could sculpt the entire editor to whatever you need in the moment. No plugin to install, no config to maintain. Just describe what you need and the editor becomes it.
