If nothing else, it’s fair to say the part of iOS that most people consider its nucleus is quickly being pushed aside.
Astute observation. Across smartphones, that’s been the point of Siri, “Okay Google”, Moto voice, lockscreen widgets, homescreen widgets, various OEMs’ “today” views, and other similar conveniences for quite some time. But, now, with Google Now on Tap and iOS 9 improvements to Siri (suggestions, always-on “Hey, Siri”) that trend is even stronger. Smartwatches, too, are promoting the idea, and capability, of using your smartphone’s homescreen less than ever.
