40 years ago when I was a kid, people already talking about this, along with space elevator, colony on Mars, flying cars, domestic robot,etc. None of these happened yet. I am sure these ideas had been around for much longer. And for the near future, this will still hold true.

It's because just like all those other things, domestic robots, flying cars and Mars colony. It's either overpriced, impractical, or both.
