Maybe this is all a way to kill Facebook. Google was able to ride the wave of the original iPhone by grafting many of the ideas on its pathetic blackberry clone OS it had before the iPhone came out. Maybe Apple is making sure Facebook wont grow to dominance of Apples VR ideas. Google certainly failed with their own already and Microsoft isnt really doing anything practical with theirs other than demos of what is possible. The longer they wait, the worse off all their competitors will be. Plus there probably needs to be some law changes made anyway. I don't see how this tech won't end up with people having better vision in the longrun. We can see how addicting smart phones are already and the effects it has on people. VR done right, paired with Ai, will change things even more drastically.
