It never happened. But why?

Prognosticating pundits of the past predicted those things because technology could make them possible. They forgot that the fact that something was possible didn't necessarily make it desirable. Technology evolves, but the human brain doesn't. The reason many futurists fail is because they forget to factor in what people want.

If you've been reading the news lately, you've no doubt heard that three amazing technologies that futurists have predicted for decades are now on the brink of being available to consumers: Flying cars, augmented reality glasses and virtual reality computers.

Yes, the technology is real. The products might even ship. But you, personally, are very unlikely to ever buy or use any of them.

Why? Because you won't want to.
