It's worth noting that the he's not afraid to us LLMs when it cuts the teacher's workload. The Slack bots are all automated.
I generally think this is okay because the students are getting more feedback, but some students are starting to call this out as hypocrisy. At Dartmouth, there's a debate running because the Provost was using LLMs to improve his writing. He's not in a class. He's not breaking any official rules. But somehow people are feeling like he's cheating.
