Apple's Macs, iPhones and Siri will get new AI brain power

Apple's Craig Federighi touts new machine learning and AI features coming to iPhones at WWDC. Your Apple hardware is about to get a notch smarter as the company builds new artificial intelligence abilities into Macs and iPhones -- and lets other programmers tap into that power. AI technology will mean Siri better understands what you want and speaks with a computer voice that Apple says sounds natural. Craig Federighi, senior vice president in charge of Mac and iPhone software, announced the AI technology Monday at the company's annual WWDC event for developers in San Jose, California. And on Macs, it'll monitor your web browsing behavior to block advertising companies from tracking some of your online behavior.
