This is exciting news for Siri. This could be a vital step in realizing the vision for Siri introduced with the iPhone 4S. I can't wait to see what the future holds for these virtual assistants.
"Apple's Siri personal assistant has lagged behind competing services like Google Now and Microsoft Cortana because of Apple's strict privacy policies and its reluctance to collect and utilize user data"
Siri does everything that I need her to do. I really haven't felt like it is falling behind Google Now and Cortana and I'm happy that Apple doesn't collect as much user data.
