Siri creator Dag Kittlaus on new virtual assistant "Viv" and future of artificial intelligence

Virtual assistant technology is rapidly spreading on smartphones and other devices, but there's a new player in the field that has caught the attention of Silicon Valley. Dag Kittlaus, one of the masterminds behind Siri, now the ubiquitous helper available on Apple products, is looking to push the boundaries of what a virtual assistant can do with his new product, dubbed "Viv" and powered by artificial intelligence. For eight months, a CNET team tested more than 40 smart home products in a first-of-its-kind "living laboratory." "So at its essence, most of the assistants that we use today do a few dozen things, so we want to open the system up and let developers build hundreds and thousands of times the number of capabilities," Kittlaus said. "So really it's an opening up of the system and letting the world teach it."
