So parent's comment was "it will be great once the tech improves" and your response is "no it won't because the tech currently sucks"? I think you're missing his point.
No, not at all. I am saying the CONCEPT sucks. It's not really a technology issue, since to overcome it we would need to be at like literally jack-in-to-the-brain, bypassing the optic nerve levels of tech. At which point we will probably have something better to do than play Half Life 3D.
