Besides El Capitan, we also learned more about
iOS 9 and its biggest feature—a smarter, more “proactive” version of Siri. Siri will soon be able to understand natural language better than before, and she’ll be able to remind you when you need to leave for an appointment, queue up your favorite jams when you hit the gym, and provide lots of other useful info before you have to ask for it.
Federighi stressed that Siri will do all of this without mining your personal data, listing all of the privacy features that Apple will uphold. “We honestly just don’t want to know,” he said.
