several levels?
initial desired technology -> useful spinoff
spaceflight -> teflon (etc)
atomic bombs -> nuclear power (etc)
I think that works reasonably well as a broad brush comparison.

==> The trouble with that, is that /if/ you regard nuclear power as a good thing then developing and using atomic bombs was a good idea. (emphasis mine)
The first non-sequitur is assuming that just because the ending spinoff is good, that the initial desired goal was also good. The atomic bomb does not have to be good in order for nuclear power to be good.
A second non-sequitur is the "and using" attachment of use to development in making the comparison. I submit there is no inherent lack of goodness in the development of atomic bombs, but there is considerable question about the goodness of using them. The use was, although perhaps inevitable, not a necessary condition for the further and positive development of the spinoff.
Finally, why is that notion if troubling?
Good Luck

What is the engineer's estimate of the military superiority gained from space superiority (to take a phrase from air superiority)?
What are the ramifications of an imbalance of space control by governments?
Is there another technology that could give military superiority that would trump space superiority? (like quantum computers breaking all other nations crypto)
While the US slept peacefully after WWI, Japan and Germany advanced military technology to dangerous superiority levels.
What is the safe level of spending to limit the disaster of that could take place if the wrong people got too much power.
I would posit that it is incumbent upon the responsible people to make sure a dangerous gap does not exist in space superiority. Of course the responsible people would take the blame for not spending the money on obvious good things for the poor and those that do not want to take care of themselves or just can't. But it is also irresponsible to not take care of those very same people by not letting the "bad guys" gain too much of a superiority.

Visigoth asked: What is the engineer's estimate of the military superiority gained from space superiority (to take a phrase from air superiority)?
I think that the first nation that establishes effective control of space and deploys large numbers of weapons in space will establish effective control of the oceans. This will give that nation the same advantages of sea power that allowed Britain to defeat Napoleonic France and the Allies to win both World Wars.
For example, what happens if China decides to invade Taiwan in 2015? The US Navy has about 250 ships. It is estimated that in ten years China's Navy will be roughly the same size as the US Navy. This would normally create a balance of power, but space-based weapons could change everything.
Imagine that China launches several hundred one-ton payloads of antishipping weapons into low Earth orbit. If China develops radar satellites (RORSATs), then they could locate US ships anywhere on the planet. The weapons would be guided by the Galileo navsats which China and Europe are building already. If China deorbited all of the weapons at the same time, then 250 US Navy ships would have at least one warhead moving at more than 7 km per second headed directly for them. Larger ships such as carriers would have multiple weapons targeting them. I do not know of any existing defense that could stop such weapons.
The US Navy could suffer a global version of Pearl Harbor. It isn't too far fetched to assume that most of the US surface Navy could be sunk or severely damaged in a single hour. American supercarriers could become the 21st century equivalent of WWII battleships: dangerous at close range but extremely vulnerable to attack by weapons with a longer range deployed from a new environment.
After that, the Chinese could take Taiwan and then blockade the Persian Gulf and take over the world's oil supply. In ten years Europe will be effectively demilitarized, so they won't be able to stop them. The Russian Navy is rusting to death. Who else has a significant Navy? Japan? India?
It isn't too fantastic to imagine the Chinese building 500 or 1000 orbital antishipping weapons. The US deployed thousands of ICBMs during the Cold War. China has demonstrated that it can launch heavy payloads into orbit. China will be the world's largest manufacturer by 2015. If they decide to outbuild the US in a new arms race, they will have many more trained engineers and a greater manufacturing capacity.
What is the US doing to meet this potential challenge? The Shuttle is grounded. Congress just authorized the purchase of two Russian spacecraft and rockets to keep the space station operating. The space station was ordered in 1984 and still isn't finished and delivered. NASA plans to go back to the moon - one year later than the Chinese, in 2018.
