Heh. I tried their rationalization step with ChatGPT, just with prompting. For their question about the fries and crackers it said the problem is flawed, because there's such a thing as crackers with low or no salt. Also correctly inferred that fries are usually salted, but don't have to be. (of course, it didn't have the picture to go by, which was the point of the research)

Great paper though. Thanks for sharing.
