I'd guess novelty seeking as a response to boredom is advantageous for learning and therefore being more adaptable to change. It might be even more of a prerequisite though - babies play, bite, and shake stuff to learn about the world. Maybe without novelty seeking you can't get enough 'training data' to have a functioning generally intelligent neural net in the first place?
