Dittoing this. All my high-value assessments are in person. If I were teaching a writing heavy course, I'd set aside class time for the writing, either by hand or in an AI-proof browser.
Yes, this requires some adaptation, but no, AI is not especially difficult to counter.
I find this discourse perplexing because the solution seems straigthforward: make university marks almost entirely dependent on lengthy in-person exams that combine handwritten essays with oral questioning.
Why is this even a conversation? Are there implementation barriers or something?
