Virtual butler 'Jarvis' takes up residence in Facebook founder's home

Mark Zuckerberg on Monday introduced the world to "Jarvis", an artificial intelligence system the Facebook chief created in his spare time, which can choose and play music, turn on lights, and recognize visitors, deciding whether to open the front door. Jarvis, named after the virtual assistant in the Iron Man movies, could be a step toward a new product, Zuckerberg wrote, although he cautioned that the system he had created in 100 hours over the last year was customized for his house. Zuckerberg announced results of the project, a personal challenge he set for himself this year, as digital home assistants by Google Inc and Amazon.com Inc compete for holiday sales and are expected to outsell popular emerging gadgets such as virtual reality headsets and drones. Creating Jarvis proved humanity is "both closer and farther off" from an AI breakthrough than we imagine, Zuckerberg wrote.
