So why are we spending all this money on "stealth" fighters if essentially other advanced countries like Russia can certainly have similar technology.
Filtering out all the noise, I suspect, is 'the hard part'. One would have to detect objects in a point cloud and determine if their paths are 'organic/random' such as animals - versus those that take more direct paths...
Stealth is just more dollars for the industrial war complex, especially if they are just going to switch to an army of remote control drones now.
Let's swap the military and NASA budgets for just one year.
NASA was the answer to last century's space race. Throwing money at it is an old, simple solution. I'd love if people came out with more ideas like the x-prize. I can get behind those new ideas.
Edit: and it's not like the military doesn't spend a ton of money on scientific and space research
