I don’t think you even know what you’re arguing about anymore. You claimed that what the author wrote wasn’t what the author thinks. As evidence you provided weak arguments about other parts of it being AI written and made an appeal to your own authority. It doesn’t matter if AI wrote that line, he wrote it, a ghost writer wrote it or a billion monkeys wrote it. He published it as his own work and you can act as if he thinks it even if you don’t otherwise trust him or the article.

Ah, I see the confusion, you're still focusing entirely on this one "this isn't just x; it's y" line. I was mostly talking about the piece as a whole, for pretty much everything other than the first sentence of my first comment above. Sincere apologies if I didn't state that clearly.
