Re: Virtual Reality
As for "showstopped bugs being worked out", do you mean the sync issues with direction getting out of sync with reality, the issues in manipulating 3D space or the objects in it (moving around or interacting with objects) or the issues of interacting in an unconstrained way with the environment (leaning or otherwise moving through a solid surface).
You've clearly only used mobile VR - the ones that use your phone. Proper desktop VR has robust tracking and positioning and the controls are mapped 1:1 within the space around you. You can pick up virtual objects with ease - it's all very intuitive and natural feeling. Don't get me wrong, there are still a LOT of issues to work out, but it is merely a matter of time before they figure them out.
Is VR "the future" of all computing? I have no idea, but I think that the technology is here to stay, even if it's just for video games and entertainment.
