Yeah it felt like it, at least. The first difference about origin and era threw me off; people in general are not interested in it and would probably not list the facts like that.
It felt uncomfortable and disingenuous reading it. I would have preferred if it ended with either “This is written by Chat-GPT” or “I used Chat-GPT then edited it”. Like the TLDR/Peertube bot on Lemmy, at least they sign it with their identity when they’re bot accounts.
