It totally comes down to the interface. When people think of computers (or, more broadly, devices), they mainly think of the screen and the inputs. If VR or AR can significantly improve on the experience of using a 2D screen + mouse, keyboard, or swipe/tap gestures, people will migrate to that superior user experience. There are plenty of other factors at play, but ultimately usability will determine if VR/AR, which are mainly new interfaces for standard computing, become the standard for computer use.
