Seems like there must be a whole lot of us white trash types out here. Because, legend has it that the digital computer was invented in the basement of the Physics Building on the campus of Iowa State University, sometime around 1940.
I seem to recall that the transistor was invented a few years later at Bell Labs.
So, by all means, please enlighten all us poor white trash types as to just how the billions spent on the manned space program are responsible for the PCs on which we bitch. And, while you're at it, clue us in on exactly why the contributions of the space program to our bitchin' machines would never have been accomplished if left to the private sector.
It was a forcing function.
