I believe the fate of Android Wear style smart watches is highly intertwined with the proliferation and usefulness of 'contextual computing' (Google Now, etc).

Glanceable cards afford great tolerance for false positives. Combining this with advances in activity detection, indoor location tracking, and IoT opens the door for a new generation of personalized software well suited for casual wearable interaction. However it remains to be seen if the economics are there to create this brave new software ecosystem.
