I would like to add that another misconception is that putting boobs on it will make us relate to it better.
Warning: Anthropologist nonsense-tangent coming up: Most matriarchal, as in dominated by women rather than men, societies don't wear clothing that emphasize the breasts, or really any other part of the body. The emphasis is less on the shape of the person and more on color (which if you want to try to make a statement about prehistoric gender roles, might fit in with a theory that men had to distinguish similarly colored animals from one another at a distance (emphasis on shape for hunting) and women had to distinguish similarly shaped vegetation from one another(emphasis on color for gathering).)
Anyways, just saying sticking boobs on something doesn't make for good girl-centered programming either.
