Experts work to turn AI robots into friendly faces

Can artificially intelligent robots be our friends? Roboticists and AI researchers are trying to make it so – and the first fruits of their labors are about to come onto the market. But there are already hints that the efforts will touch some of humanity's hot buttons. Take Hanson Robotics, for example: Its latest creation, Sophia, combines an AI chatbot with an expressive humanlike face. She can talk enthusiastically about helping humans in health care, education and customer service.
