I don't think the USA gets enough credit for inventing this hybrid economic development system. Good examples include:
* Military computing -> Intel, IBM, etc. -> Moore's law
* DARPA cash -> early networking/PC projects at universities -> hacker/hobbyist culture -> Microsoft and Apple
* Gov't really emphasized "finding information" in CS the 1990's -> NSF grants at Stanford -> Google.
* The Human Genome Project -> Illumina, Solexa, etc. -> Moore's law-shaped cost curve for sequencing
And less R&D heavy examples like the national railways and the interstate highway system.
This pattern continues today. Self-driving cars started as several decades of NSF-funded research projects that turned into a DARPA-funded competition a decade-ish ago that turned into an industry-funded goal rush today.
