I don't know what to say except that this has not been the case for me. Claude is a different person for every single prompt and has absolutely no core sense of what our goals are, or even who the "our" is that's having goals.

While my coworkers are very stable personalities of a consistent work drive, sense of pragmatism, things that they find more and less interesting, career aspirations, etc. they're not all the exact same, and I depend on that as I fit tasks and ownership to people.
