Tain't no count lest the GUMMINT funds it!
Because, ya know, it’s GOD.
The space program is the only possible exception. There were a bunch of things that were claimed to be from the space program, but I know of few if any widely used technologies that were not mainly from good old terrestrial free enterprise. Even the internet really didn’t get to the scope it has now until the private firms started jumping in for the sake of, argh, the money.
Well... I could also count in military efforts. Because of all the whizbang missiles and such, we do have better civilian electronics. War and defense are legitimate constitutional duties. The mail is as well, but I don’t think the USPS really strained technology to the point it had to be evolved. I don’t know about space exploration, but there is something to be said for the seemliness of having it coordinated on a national and international level, lest every Tom, Dick, and Harry fill the stratosphere with space junk.
