The USA version of a modern PC, overseas the brits were fiddling with their own versions. It was only possible because the govt spent loads of money financing companies into creating electronics. If not for the USA govt needs and the competition arising from that, its unlikely Silicon Valley would be what it is today, and Steves Wozniak and Jobs probably wouldn’t have access to cheap chips.
Linux was a pet project
Of a university student, not an entrepreneur, and something he did because he didn’t want to pay for a license of MINIX, not for financial gain.
Uber
Is a piece of shit that just tacked together existing technologies and abused a completely unregulated space to grow and dominate the market.
SpaceX
Wouldn’t exist if the USA gov’t didn’t get its shit together after the initial successes of the URSS’s space program. Look how long it took until private companies began bothering with space without direct funding from a government.
There are thousands of entrepreneurs that prove you wrong on that point.
Most of them relying either directly or indirectly on the shoulders of gov’t funded innovation that likely wouldn’t have happened otherwise, especially any company dealing with space. The internet would either have taken longer to develop or be much different without the ARPA Net as a forerunner, for instance. Most of its innovation afterwards came from universities, not entrepreneurs. More often than not, entrepreneurs take existing technologies and find a way to profit on top of them.
