Yeah, I share this same sentiment about the author. His inability to see why his wife was actually upset by his behavior is astounding. I'm going to wager that she very much meant to say that she thought he would be incessantly argumentative with the AI as well, and when he wasn't it surprised her because she suddenly realized that it was only her that he was like that with and it became very personal for her.
I think that part may have been misunderstood. My wife wasn’t upset about me being argumentative, her point was that it bothered her I was convinced by the AI, rather than by her, and what stuck with me is how quickly I was convinced by AI and stopped dead in my tracks. That is why I wrote the piece.
