The article boils down (pun intended) to, “you already accept all these things which I am glossing as basically instant mashed potatoes, so you should also accept LLMs.”

That’s why they not-so-subtly start calling them IMPs when they introduce the “abstracted version.”

It’s not merely an example. It’s the thesis of the article.

EDIT: Out of perversity, I skimmed the comments. The audience of Astral Codex Ten seems to share this interpretation, for whatever that’s worth.
