I have had a similar experience using ChatGPT to build https://meoweler.com – a travel website covering 5000+ cities with a surprisingly good content quality created over a long weekend. Something that was unfathomable for me 2 years ago.
I checked the city I live in and three more cities I know quite well, and I have to disagree. This reads/feels like a content farm, which (if GPT wrote the content, as you seem to imply) is exactly what it is (as I have excessive Adblock I don't know if there are ads, but I don't think they are needed for the definition of a content farm).
And there are no ads. It's really more of an experiment rather than a real product.
