These systems don't have a genuine capacity of introspection, beyond just mining the conversation trace. When you're asking them why they did this or that, they are basically guessing anew from the outside, and are just as likely to hallucinate as they are to hit the right answer. These are mechanical systems which brute-force chains of various (re)combinations of techniques acquired from the training data. The true authors are all those who have contributed those techniques in the past.
