I agree you shouldn't use LLMs to produce material wholesale, but I think it can be positively useful when used thoughtfully.

I recently taught a high school equivalent philosophy class, and wanted to design an exercise for my students to allocate a limited number of organs to recipients that were not directly comparable. I asked an LLM to generate recipient profiles for the students to choose between. First pass, the recipients all needed different organs, which kind of ruined the point of the dilemma! I told it so, and second pass was great.

Even with the extra handholding, the LLM made good materials faster than if I would have designed them manually. But if I had trusted it blindly, the materials would have been useless.
