A Feeble Younger Brother
Sony has one of its Qrio robots attending a human nursery school in San Diego.
"While the children were at first apprehensive about Qrio, they now dance with it and help it get up when it falls. "The children think of Qrio as a feeble younger brother," researcher Fumihide Tanaka said."
As a parent, I wouldn't be too happy about putting my children in that situation, but I suppose that it might actually be good for the kids.
After all, when the killer robots descended from their "feeble younger brother" decide to terminate humanity, they might show mercy to the old playmates of their youth.
