Yeah, and to be blunt, beige and not dynamic is how I would describe most student writing done entirely by the human. I just don't see how a model, trained on a vast corpus of such writing, could ever be successfully and reliably distinguished from human writing. You can distinguish good writing from so-so writing, that's about it.

In an educational context, the only purpose of the writing has traditionally been learning, and the purpose of turning it in has been to prove that the learning took place. Both of those are out the window now. Classroom discussion and oral presentations might be the only place you can still prove learning took place. Until everybody gets hidden AI-powered earpieces of course.
