We feel safe thinking machines have no heart, but actually, men give machines hearts. A loyal heart, innocent devotion, and self sacrifice are the machines’ essence. It’s like a dog obeying the orders of a master no matter how evil the master is. I think the thought that humans give hearts to machines is the base of Asimov’s “Three Rules of Robotics.” The God Warrior in Nausicaa is not that original an idea. The design, too, you can find its root in many preexisting designs. But, the moment I gave a tangible shape to “innocence,” it became something I can’t control. I think I gave it a shape because I have a strong yearning for innocent ones...
