I wouldn't have picked this article as AI until I got an agent to do some writing for me and read a bunch of it to figure out if I can stand behind it. Now I see the tells everywhere "It's not this. It's that." is particularly common and I can't unsee it. (FWIW I rewrote most of the writing it generated, but it did help me figure out my structure and narrative)

The problem I think with AI generated posts is that you feel like you can't trust the content once it's AI. It could be partly hallucinated, or misrepresented.
