Good question. I think not, but who knows?
I suspect they could, although accuracy might take the hit relative to how much other data they had.
I believe that they could extrapolate or interpolate information and the accuracy would be based on how many data points they would have. So first, have a long conversation with AI, then buy a person’s data profile, throw in their medical records, internet... ahem.. habits, and all social media activity and I think you could have a superb model with high accuracy for any questions asked.
