Maybe? We have learned a lot about the brain in recent times. You can, today, hack your way into controlling a mouse with your mind. That's all external and, of course, requires a headset.

I doubt I'll be alive to see it, but it seems that is the most probable method to get mass adoption of VR. Right now, it is really niche. Right now, we are still trying to do it the way we've been doing it for the past three decades. Things are faster and smaller but there are limits to those two traits.

I'd absolutely love AR. I have a modest collection of automobiles and sometimes work on them. I sometimes make things out of wood. I sometimes can't identify an animal species or plant family. Having the ability to augment that would be a wonderful way to enjoy life even more - at least for me.

But, even if we got these down to the size of eyeglasses (which seems really unlikely for the foreseeable future) I'm not sure we will get mass adoption by Jane Q. Public. It's not a cell phone you pick up and put away, but something worn. The form factor is, by itself, a negative.

I dunno? I can't predict the future. I'd still volunteer to test a viable method. With the ubiquity of cellular network connectivity, it'd be fantastic to have the sum of human knowledge at your immediate beck and call and without the need for an external device.
