I'm a long time Yegge fan and follower and while I think he's still in the vibe code honeymoon phase and hasn't had the vibe code hangover yet, his bona fides on emacs are up there with anyones.

It was my observation around 12-18 momths ago that LLMs are weirdly good at elisp (which kicked off all the // hypermodern stuff I'm doing.

I think he's onto something with efrit, I havent gotten it dialed yet but its reaaallyy promising.
