Have you heard of Magic Leap, one of the most secretive startup. Currently, they are looking at a valuation of $8bn. This is from Wiki – Magic Leap is a US startup company that is working on a head-mounted virtual retinal display which superimposes 3D computer-generated imagery over real world objects, by projecting a digital light field into the user’s eye,[1][2] involving technologies potentially suited to applications in augmented reality and computer vision. It is attempting to construct a light-field chip using silicon photonics.[3]
Magic Leap may fail. It may fail spectacularly, in the kind of blowup that makes for a great business tale. Or it may fail only in its ambition to be the Apple of augmented reality — and instead become yet another technology company powering devices and services that help Alibaba to better compete with Microsoft and Facebook. It’s also possible that it may succeed spectacularly.

Which means that somebody may be able to fool people in one location at a given time.
Then reality kicks in! And then what? To lend a word from an outstanding president (in his own eyes):
Creating the perfect ‘fake world’!? Why? No matter what, we do have to live in RL/RW and fix it’s shortcomings as we go!
