Yes, I can be serious, and practice doesn't use them differently.
VR/AR has been seen as one thing by pioneers like Sutherland and
all practical applications of VR did not include autistic HMD
operators. Stanislaw Lem treated the whole problem space pretty
thoroughly in 1970s, actually. It's too bad he's virtually unknown
in the US.

Yes, you already said that, but it's not true. VR isn't Jaron Lanier
with cyberglove and Polehemus HMD in front of an SGI SkyRise.
That's so overspecified it's a caricature.

Advanced AR is a mirror world overlay over the real world. Eventually,
the mirror worlds will become richer than reality.

The overlay rendered is a synthetic world. It's an aligned VR overlay,
where the mirror world you see happens to fit the geography.

Yes, sufficiently sparse datasets are useless. I agree.

That's an orthogonal issue to the concept.

The opposite is true, non-aligned VR has a continous vector towards
real AR, aka Artificial Reality. Augmented Reality is a dead end, however.
Augmented Reality always assumes a monkey in the loop. Artificial Reality

Again, you're using different words for the same thing. Anchor a SL
world to physical terrain with a HUD and it's exactly AR.

Implementations are just great. I love implementations of hitherto sterile
However, implementations per se do not result in novelty. What I'm looking
for is concepts that will become implementations some 20, 30, 50 years hence.
The concepts I'm not yet aware of, I mean.
What do you think does exist today that will become great in 50 years?
