While it’s interesting work, so far my experience is that AI isn’t good enough (or most people aren’t good enough with AI) for detection to really be a concern, at least in “research” or any writing over a few sentences.

If you think about the 2x2 of “Good” vs “By AI”, you only really care about the case when something it good work that an AI did, and then only when catching cheaters, as opposed to deriving some utility.

If it’s bad, who cares if it’s AI or not, and most AI is pretty obvious thoughtless slop, and most people that use it aren’t paying attention to mask that, so I guess what I’m saying is for most cases one could just set a quality bar and see if the work passes.

I think maybe a difference AI brings is that in many cases people don’t really know how to understand or judge the quality of what they are reading, or are to lazy to, so have substituted as proxies for quality the same structural cues that AI now uses. So if you’re used to saying “it’s well formatted, lots of bulleted lists, no spelling mistakes, good use of adjectives, must be good”, now you have to actually read it and think about it to know.
