Talk of artificial intelligence often leads to speculation about how machines may displace workers. Microsoft CEO Satya Nadella thinks we should talk more about how AI algorithms can expand the workforce now--by helping people with disabilities. "There are a billion people in the world who don't fully participate in our economies or societies," Nadella said, at the WIRED25 Summit in San Francisco. "Technology can allow them to fully participate." Nadella, a WIRED25 Icon, nominated Jenny Lay-Flurrie, Microsoft's chief accessibility officer, as someone who will shape the next 25 years of technology.
