for iPhones maybe not but for drones or AR devices if you want to stream 4k at 60fps or 120fps then there is a lot of data to send. You could use iPhone as Drone payload for doing some site/construction inspection etc. Same with drones - they can fly very fast so would be nice to stream at 4k@120fps. Drones or iphones can/have many camera including lidar, depthmap (trudepth)

That is only the case if you wanted to stream uncompressed data (which for drones is defeinitely not needed), so VR/AR maybe, anything else it would be a waste.

  compressing big video frames (4k) takes time. If your application is latency critical (and drones moving at 100km/h is) and you are streaming at 120fps you have only 8ms for video frame processing. Sometimes you also want uncompressed data (lidar, depthmap) not for human but for machine computer vision / processing.

...Then what was the point of specifically calling out the 2x2 MIMO antennae of the iPhone?

  that 9.6Gbps speed mentioned in the article doesn't apply for most consumer devices because they have only 2 antennas. Only expensive routers have many antennas to reach such speed. Not sure if we can have 8 antennas in smartphones
