Microsoft's expanding its AI into search, email, Office and apps

Microsoft AI chief Harry Shum says the company is fulfilling Bill Gates' vision of a computer that can understand us. If you ask Google "Is Hamilton a good musical?" it will send back a link to Quora, the question-and-answer service, where people ask that same question. The next link, a story published in Slate last year, is an interview with a critic who argues why the Pulitzer-, Grammy- and Tony-winning musical isn't revolutionary (their pun, not ours). Microsoft thinks it can do better. Beginning Wednesday, the company will start giving you more nuanced answers, powered by artificial intelligence software designed to identify different viewpoints.
