Well, it cant be that he is super worried on behalf of people who publish AI slop. That’s not a credible motivation. In fact, he complained a lot about the new ChatGPT app so I can’t believe your claim that he is not using AI.
Seems like he really likes to use LLMs and is worried that quality will be degraded. But he will never demonstrate such degradation scientifically, we don’t have anecdotes even.
