Apple is shipping the core pieces of an AR headset today to hundreds of millions of users
Apple will ship nearly 100 million depth sensors in 2018/2019. They have successfully miniaturized (with a low cost BOM) the fundamental sensor for inside-out positional tracking of any headmounted VR/AR device
(I sincerely cheer and hope for Microsoft & MagicLeap to succeed!)
This will truly be Apple's first post-Steve Jobs product and I think they will absolutely dominate.
