AirPods Are A New Device Platform
AirPods are truly self contained computers that soon will have their own apps, primarily centered around the Siri Intent Domains [7], but at some point beyond this. A rich development environment will grow around Siri and intend to unique features that only in-ear devices like AirPods can create. The double tap to activate Siri will over time become one of the most powerful aspects to AirPods and its successors. At some point this will morph into an entire device platform of its own and ultimately require less or no tethering to an iOS device or a computer. It all started with AirPods.
Essentially the author postulates that Airpods will take over as the primary voice only device that provides augmented reality via Siri - like an audio version of Google Glass.
Fantasy or prophecy? Who knows. Not sure I would prefer audio over visual myself considering I don’t even use Siri.
