Nice article, but in my perception, Apple is way behind in AI vs. Google on mobile. Siri's current speech recognition is still far behind Google on my iPhone. Half of the time it Siri doesn't recognize something but Google recognizes it right way. Apple Maps continues to lag in the following features: biking and public transit and even things like which lane to take on a big interchange. As a result I end up using Google (Now) and Google Maps by default.
