To me, the amazing thing is that so much that was science fiction back then, political fiction, today is reality. We have indeed a spacecraft called an international space station. And we have the diversity of this planet working on that ship, including Americans and Russians working side by side. I think the imagineers are the ones that set the goal. And the inventors and the technicians see that as a goal to work toward, or the political scientists and the diplomats. And eventually, that's arrived at.
