Flying cars are what comes next after cars, and that's been going on for several decades now isn't it?

VR does have great potential, but not as it is right now. IBM and Xerox have put in a lot of money then in a lot of things. And Google is throwing money at several things too. But seldom do the big wave things pan out as expected when we want them to.

Some things require major scientific or technological breakthroughs. Other things just require smart people and people with money willing to take a chance on them. Flying cars falls into the former (needs battery breakthrough). I think VR falls into the latter.
