> my girlfriend is a teacher and for the past year ChatGPT has allowed her to augment her lesson plans with slides/games/etc that have had a very positive effect on student engagement.

My wife, who is also a teacher, does the same thing. I think this is an underrated use of AI right now. There's also been a new wave of edtech companies focusing on AI as the teacher, which I'm skeptical will reach product market fit. I think AI as the teacher assistant could be interesting though.
