I own some glasses that function as if you're watching a standard definition television set that's a few feet on on a side from about 10 feet away. So, I could be watching porn or an R-rated movie, and nobody would care.

Bring on the tech, I say. I can't think of any tech that's thought of as being at a dead end in terms of possible progress. We've got at least a decade to enjoy Moore's Law, and there's plenty of things that technology could do that hasn't happened yet.
