Yann LeCunn of New York University

Facebook's fledgling artificial intelligence group now has a leader -- the social network has hired New York University professor Yann LeCun to run the research division from New York City. He'll remain at the university part time, but most of his energy will now be spent researching data science, deep learning and other technologies that could refine Facebook's social stream. While LeCun's hire won't pay off for some time, it already suggests that Zuckerberg and crew are serious about competing with Google's Ray Kurzweil in the AI space.
