Not sure what others have been reading so far, but this article already smells so human, I couldn't imagine anyone mistaken it for LLM output (especially since it is about LLMs and how they fail to work for some of us).
Funnily enough I also consulted three models across different vendors, and all came to the same conclusion (it's very human and very unlikely LLM produced). And yes, I let them all cross reference with older posts which are all pre-LLM era. Takes less than 5 minutes to do so.
