We'll just have to wait until pschyohistory is invented.

A charitable way to read this site is to use it as a way of talking about current trends. For example, they say "Male and female salaries are reaching parity" in 2067. Who knows what'll happen, but it's a novel way of talking about just how far behind female salaries are and at what rate they're changing today. For another, projecting Moore's law out to 2083 is silly, but it is interesting to remember how transistors (and other computer parts) have been shrinking exponentially through the present.
Could people living at the height of the space race realistically predict the collapse of American space exploration? Could they see coming the subsequent rise of private space ventures?
