Yes, but only for certain kinds of creativity. Hacking requires a lot of creativity, but there's not a tremendous amount of emotional content in it, so it doesn't really demand vulnerability. Even a lot of very creative musicians write from the head more than the heart (e.g., Frank Zappa, Robert Fripp, others).
A lot of artists, however, try to explore and express something about the human experience. That kind of creativity demands vulnerability, because you have to be sensitive and introspective enough to be able to channel that emotion into some kind of medium.
