We spend enormous energy protecting bank statements at some level, treating them as surveillance risks. Yet people voluntarily share with AI systems something far more revealing: how they actually think, what they believe, what they are uncertain about, etc. A bank statement can tell you someone eats at the same place twice a week. But a long AI conversation tells you how their thinking drifts, what they are afraid of, what kinds of arguments move them, and thoughts they would never say out loud. I think the most sensitive data is no longer behavioural.
