Why Apple Joined Rivals Amazon, Google, Microsoft In AI Partnership

Apple is pushing past its famous secrecy for the sake of artificial intelligence. In December, the Cupertino tech giant quietly published its first AI research paper. Now, it's joining the Partnership on AI, an industry nonprofit group founded by some of its biggest rivals, including Microsoft, Google and Amazon. On Friday, the partnership announced that Apple's head of advanced development for Siri, Tom Gruber, is joining its board. Gruber has been at Apple since 2010 when the iPhone maker bought Siri, the company he cofounded and where he served as CTO.
