True, but some of those space predictions may come true sooner rather later now largely thanks to Elon and SpaceX. For example, a startup called Positron Dynamics has a serious proposal for an antimatter rocket. If it works, that would likely open up the solar system to human exploration. I doubt they would have gotten funding without the renewed excitement around space.
