General Discussion

I think this is about the physical inventory, like planes

Also Personally Identifying Information is not part of a legitimate training set for the AI tools themselves. If "AI companies" are buying this data, they are almost certainly receiving it as anonymized (or doing so immediately upon receipt thereof, and deleting the original sets containing PII quickly).

PII is a HUGE liability, and not useful for actual model training anyway. You want the info to look like "Person146236568, male, about 45 yo, high income, good credit score, lives in Phoenix", not "johnsmith@yahoo.com, 123 Pleasant Street, Phoenix, AZ, 480-234-5234". Possession of the former has 0 legal liability, but the latter conveys a LOT of liability, with 0 tangible training benefit.

Now, what some bad actors are leveraging trained AI models to DO in terms of analyzing data sets containing PII for their own nefarious purposes is another question/subject.
