It's not great for the teacher though. They're the ones who will truly suffer from the proliferation of AI - increased complexity of work around spotting cheating 'solved' by a huge increase in time pressure. Faced with that teachers will have three options: accept AI detection as gospel without appeals and be accused of unfairness or being bad at the job by parents, spend time on appeals to the detriment of other duties leading to more accusations of being bad at the job, or leave teaching and get an easier (and probably less stressful and higher paid) job. Given those choices I'd pick the third option.
