I have opposite version of this problem.

Is it possible for AI to learn so much about myself that it will be more me than me myself?

An AI could potentially accumulate detailed information about your behaviors, preferences, communication patterns, and decision-making tendencies - perhaps even more comprehensive data than you consciously remember about yourself. It might predict your responses or model your thinking patterns with impressive accuracy. An AI might become very good at simulating aspects of "you" - perhaps even better than you are at articulating your own patterns.

It could create high probability "coherent action paths" of what I might do in future given current context. Then matching my initial choices to see which action path I am on, it could in theory "predict" my choices further down the line. Similar to how we play chess.

Is stagnation a goal?
