What??
NASA and Manhattan Project never invented anything (I assume you mean anything useful)?
Try to use not-so-obviously-false facts to support your position.
First and foremost, there are probably over 5,000 NASA-contractor patents sitting right in front of you as you typed that drivel.
Where the hell do you think the INTEGRATED CIRCUIT came from? You think mom an dad, the progressive consumers, expressed a sudden desire to have their refrigerators do something fancier than cool and demanded them?
How about the GPS? Use OnStar?
In the '80s I went to two of ten trade shows called Technology 2000 and Technology 2001. This was an effort to make dual use (civilian and military) of government-invented technologies. It was big and crowded.
Can you say Raytheon?
You can't be awake for more than 20 minutes without stumbling over something invented at Raytheon.
If it weren't for NASA and all the other gubmint agencies and their contractors, oh, Martin Marietta, Lockheed, Boeing, United Technologies, Allied/Bendix, NIH, Abbott Laboratories (I'd go on, but I don't have all day), you'd never have seen the microwave oven, CAT scans, MRI scans, most new lifesaving drugs (that needed studies to show they work).
The gun you paid $600 for would cost you $6,000.
Y'see, I'm not talking out my a$$ here. I have been an employee of some of these gubmint contractors. I know where all the goodies you like to play with every day came from. About 8 out of 10 times you fly in a 737, 757, or 767, my initials fly along with you, microscopically etched into three or four integrated circuits (it's an industry tradition) that help the pilot fly the plane.
Even the Manhattan project. How do you think they figured out how to obtain all that "nuculer" stuff that makes some of your electric power? Just because things nuclear are very controlled and you never get to see them, doesn't mean they don't do a lot of stuff for you. They tell you whether the bridges you cross are supported by sound structure without having to rip into them. They diagnose medical illness, and treat some of it too.
That was just too wild a statement to let pass.
