Yeah I also havent seen anything being done. There is a basic plugin for copilot but nothing more from what I know. I guess seeing something like Copilot X in Emacs would be cool. I think it might be due to power-users of Emacs possibly being a bit more old school, and maybe even a bit in opposition to the changes that LLMs are bringing? Might be also that, if userbase is more experienced engineers, they are just waiting for the whole space to stabilise more.
