Musing over the possible hierachy of humans and humanoids, Takeo Kanade, the director of the Robotics Institute at Carnegie Mellon University in Pittsburgh and an expert in vision systems, posits, "We are facing the fact that we may not be, any longer, the single entity that does a better job in all aspects. How we as human beings will react to it, I don't know. But we are surpassed by many artificial things already. We don't mind that we have turned computing numbers over to machines; humans are not afraid of that at all."
