The goal of writing papers for classes is not to produce the output, but to synthesize the information in your own words. The output is used to simply be a proof of the process, thats what teachers are after. I don't think synthesizing different sources and writing the output is an invalid pedagogical tool.
Discussion
What does the process teach? How to relate one concept to another? Why are papers grades if we are after teaching the process? If everyone learns at their own pace, shouldn’t grading be irrelevant?
Oh yeah, grading is a bad system. However, writing is an excellent way to clarify and improve your thinking skills. Cheating yourself of that with chat bots is stupid in my opinion. However, the system is often seen as transactional, i produce the output for you to give me a grade or a title.
If you want to actually learn, however, writing and having that writing evaluated and receiving feedback by a person that is accomplished in the field of study you are writing about is an excellent pedagogical tool.
Arguing for using llms in that context is like saying that running a mile has no benefit because we have cars to get us there faster. It's not about the output.
