Which Google has made exactly zero progress towards. Google Now has access to a lot more data and is a lot more useful than Siri, but if you curse at Siri for doing something wrong, she (it? they should really gender AI's.. helps with bonding) says she was only trying to help. Ask her if she watches GoT.. she gives you a quip about Lannisters. If I ask her what track is playing, she says 'let me have a listen'. Google Now just gives a beep and displays a bouncy colored wave. I can ask Siri 'do I need to wear a jacket tommorow' and it'll give me the forecast. Google just displays a search result with that particular sentence.
