I am not sure if you are familiar with Pangram (co-founder here) but we are a group of research scientists who have made significant progress in this problem space. If your mental model of AI detectors is still GPTZero or the ones that say the declaration of independence is AI, then you probably haven't seen how much better they've gotten.

This paper by economists from the University of Chicago economists found zero false positives of 1,992 human-written documents and over 99% recall in detecting AI documents. https://papers.ssrn.com/sol3/papers.cfm?abstract_id=5407424

AI detectors are only harmful if you use them to convict people, it isn't harmful to gather statistics like this. They didn't find many AI written paper, just AI written peer reviews, which is what you would expect since not many would generate their whole paper submissions while peer reviews are thankless work.

I think there is a funny bit of mental gymnastics that goes on here sometimes, definitely. LLM skeptics (which I'm not saying the Pangram folks are in particular) would say: "LLMs are unreliable and therefore useless, it's producing slop at great cost to the environment and other people." But if a study comes out that confirms their biases and uses an LLM in the process, or if they themselves use an LLM to identify -- or in many cases just validate their preconceived notion -- that something was drafted using an LLM, then all the sudden things are above board.
