Also maybe losing all scientists to America and half of the country to Russia for 30 years might have contributed here. A cultural aspect may be that Americans are more willing to try and fail, which in software has almost zero cost. In engineering it's an advantage to be risk-averse. In software where "building" is automated, and barely a factor. Theory almost equals practice here. So it's cheaper to practice.
