Furthermore, I have no doubt that Apple has people doing work in all sorts of adjacent markets like AR, VR, more wearables etc. But the consensus seems to be that it's going to take a lot of things coming together for true mainstream products in AR for example. And for better or worse releasing effectively a version 0.6-type product to test the waters just isn't Apple's style (at least deliberately).It's not just a matter of no company has invested enough money yet.
