Most people don't know what they're interested in and consumers are starting to actually take hold of AR. Ever seen Snapchat filters? Yep those are 3D tracking with depth. Not fiducial AR or just non tracked "overlay" so it counts. It's steps toward HMD AR by showing people what is possible to do to changing the real world dynamically.

Having hardware that can do depth at scale with an application layer is a big step - not sure that the 7 plus gets there but it's a start.
