That is a far cry from, "We wouldn't have commercial aircraft or anything requiring a microchip without government funded research."
For years and years after Noyce (who was funded by Sherman Fairchild from his camera business) and then National Semiconductor really got the ball rolling, they were swimming in private venture capital.
It is demand, not government, that has propelled the semiconductor industry. That is undeniable.
The government is more interested in specialty chips, many of which are hybrid (part integrated and part discrete component). That is for their unique use and therefore unique requirements such as the environment of space and reentry or the high speed, high heat environments of missiles.
They did aparently make a sudden move on a computer company that had a huge breakthrough in processor speed. That company went from "rising megastar" to "you never heard another word about them".
