So, whatever brain scientists may or may not eventually come up with, it seems pretty clear already that female type humans can be just as good at both conducting and composing as male type humans. That is, there are already talented, successful women working in both fields, people who are respected and admired and enjoyed as much as any of their male colleagues.

Whether or not the playing field is level is a sociological question, and whether brain science ever has anything to say about that is an open question. (As it were!)
