I’ve spent two years arguing that AI detection tools are close to worthless. I still think the studies showing they flag non-native English speakers at higher rates are damning, and I still think any university disciplining a student on the strength of a probability score is committing an injustice it will eventually have to apologize for. None of that has changed. But there’s a category of case where the objection collapses, and we just watched a clean example of it.
