Yeah. This is a way bigger problem with this article than anything else. The entier thing hinges on their AI-detecting AI working. I have looked into how effective these kinds of tools are because it has come up at my work, and independent review of them suggests they’re, like, 3-5 times worse than the (already pretty bad) accuracy rates they claim, and disproportionatly flag non-native English speakers as AI generated. So, I’m highly skeptical of this claim as well.
