The initial products in a new medium are successful products from the prior medium copied and forced into the new medium. It’s easier for people to imagine and fit a mental model of the new medium that is still developing. I often hear that AR will be great “to see my Uber approaching” (even though a 2D map does a great job of this). The winning AR apps will take advantage of the new capabilities of the new medium and do things that weren’t even possible in the old medium.
