If Apple's AR headset is successful who will buy iPads and iPhones anymore? As a company you have to be the one making yourself obsolete all the time to innovate and survive, because if you don't, then other companies will. Fear of cannibalizing existing profitable products with new ones, is what killed Nokia, Kodak, SGI, Blackberry, Philips, etc. leaving them as husks leapfrogged by more brash competitors.
