> but "nothing" is an overstatement

Absolutely not. There was genuinely nothing in their thoughtful and informative reply that seemed AI generated to me. Have you never seen people on HN write detailed, articulate answers? This was one of them.

Asking a question, getting a helpful response, and then implying it was written by AI is quite rude. Saying, "Excuse me if not, $SOMETHING_VERY_OFFENSIVE" does not make "$SOMETHING_VERY_OFFENSIVE" any less offensive! It's disheartening to see someone take the time to write a great answer only to be met with such a rude question. Please don't do that here. It's frustrating and discourages genuine contributors.
