Should robots be manufactured in our own likeness?

Humanoid robots are a familiar trope in popular culture, but is making machines look like us a little bit creepy and even potentially dangerous? Whether it is Isaac Asimov’s robotics novels, 1980s movie character Johnny 5, Hollywood’s Avengers: The Age of Ultron or Channel 4’s sci-fi drama Humans, there has long been a fascination in popular culture with robots becoming sentient - beings that can experience feelings and human-like consciousness. But how realistic - and desirable - is the prospect of robots that become almost indistinguishable from humans? Dr Ben Goertzel, who developed the AI software for Sophia, a social humanoid robot made by Hong Kong-based Hanson Robotics, believes robots should look like humans to help “break down suspicions and reservations people might have” about interacting with them. “You will have humanoid robots because people like them,” he tells the BBC. “They’d rather give orders or complain about their girlfriend to a humanoid robot rather than to the Roomba .” “I think Pepper robot is very ugly. It is sort of like a rolling kiosk. Sophia will look you in the eye, it will mirror your facial movements. It’s a different experience than looking at a screen on Pepper’s chest.” There are now 20 Sophia robots in existence, and six of them are being used around the world to give speeches and demonstrate the technology. Companies have approached Hanson Robotics with an interest in using Sophia to greet their customers, but humanoid robots like Sophia and Pepper are still very expensive to manufacture, Dr Goertzel admits. Many roboticists disagree with his approach. Dor Skuler, co-founder and chief executive of Intuition Robotics, is strongly opposed to robots looking or sounding like humans. His firm makes ElliQ, a small social home robot for the elderly that aims to combat loneliness. It can talk and answer questions, but it takes pains to remind users continuously that it is a machine, not a human. He is concerned about the “Uncanny Valley” effect - Masahiro Mori’s idea that the more closely robots resemble humans, the more we’ll find them creepy and revolting. And he thinks it is ethically wrong for robots to pretend to be human. Inevitably people will always realise that the robot is not real, he argues, and they will then feel betrayed: “I do not see the link between trying to fool you and trying to give you what you need. “ElliQ is cute, and it is a friend. From our research, an objected can still create positive affinity and alleviate loneliness without needing to pretend to be human.” Dr Reid Simmons, a research professor at Carnegie Mellon University’s Robotics Institute and director of its undergraduate AI degree, agrees. “What a lot of us believe is that it is sufficient for a robot to have rudimentary characteristics of human gaze and gesture, without having to go to hyper-realistic human form. “I’m a strong believer that we need to stay away from the Uncanny Valley, because it sets up expectations that the technology cannot deliver.” But Dr Goertzel, who founded SingularityNet, a marketplace for AI that enables programmers to develop and sell AI apps for use in robots like Sophia, believes that robots will eventually become as smart - if not smarter - than humans. And the more we see humanoid versions around, the quicker we will get used to them. Sometimes people feel easier confiding in a non-human machine, he suggests. But will we ever reach that sci-fi point where robots gain consciousness, freedom of choice, and perhaps rights under the law? “I think that if robots have the same intelligence as humans, then they will have the same consciousness,” says Dr Goertzel. –BBC
