I have misguided friends working with payment processors (think companies like VISA, mastercard, etc.) to build models that run across all transactions to extract the purchasing behaviors of individuals, uncover correlations between accounts for marketing purposes, and predictively model future purchases and life events. Surveillance is inescapable at this point. How long until AI shops for us based on past purchases or we live in a world where mass individualized price discrimination is the norm? How to avoid that future? Sometimes I forget privacy is a basic right, as society often requires that we sign it away.
