My understanding of the context is the author is no longer using Emacs, and is very excited about the productivity from AI.

My experience with LLM technologies is it does make generating the code a really quick part. It may be reasonable to take much more time to specify things up front (rather than emergently as you would by hand). -- I mean, if you've got a well crafted description of what you want, you'll be able to get a working program MUCH quicker with an LLM, today, compared to writing it out by hand.

Would it really be surprising/shocking if an LLM was able to rewrite (most) features from an existing software, to a new software?

It seems like the reality today is, we've gone from a maintained software in a niche ecosystem with happy users, to a more fragmented one where everyone has an LLM write their own half-baked one.
