Yes, I do I grew up during the cold war and the height of the space program. Most of the innovations you mention grew out of the defense program and were the result of long term funding.
I am referring to the stimulus programs where the president picks an industry and throws some money at it. Once the taxpayer dollars have been spent and there is no public demand for the product then where are are you now? You sell to China and the taxpayers are out of luck.
BTW, you might want to reread the last part of my original post on this subject. You seemed to not have gotten the point.
