Ignoring for the moment the accuracy of that tool, even if the prose is 99% AI written, that doesn't meant that the result is fake. Maybe their model wrote it.
100% had this thought because of the repetition. It generally just feels like it makes the same point three times without adding anything new in any of them.
Hi! I am the person that wrote this, and used GPT-3 and a few other writing tools to help me wordsmith it. All the points, however, is original work and not AI generated. I am not a native English speaker, so I have been using these tools to avoid awkward sentences/paragraphs. (Clearly this has not been the outcome I was hoping for)
Citing without linking is something I've seen ChatGPT do. It knows this sort of article should contain this sort of citation but doesn't know or care what to actually link.
The second half of the article seems more authentic though. I'm not sure ChatGPT would come up with "the middle class comes from economic friction" (paraphrasing).
