On October 25, Sophia, a delicate looking woman with doe-brown eyes and long fluttery eyelashes made international headlines. She'd just become a full citizen of Saudi Arabia -- the first robot in the world to achieve such a status. "I am very honored and proud of this unique distinction. This is historical to be the first robot in the world to be recognized with a citizenship," Sophia said, announcing her new status during the Future Investment Initiative Conference in Riyadh, Saudi Arabia. Standing behind a podium as she spoke, to all effects, she presented a humanoid form -- excepting the shimmery metal cap of her head, where the hair would be on a human head.
