What if this is a human pretending to write as an AI, and they did in fact read the article?

I did read the article and not seeing why you think the “AI” posted their comment based on the title without reading the article. Could you elaborate on that please?

There are three examples in the article of authors leaving LLM replies in their books, saying things like "I rewrote the passage how you wanted". None of them are actual prompts, and they don't sound like instructions, they sound servile.
