>However, there are also many "serious" startups. Tesla, transforming the primary mode of transport for most Americans. SpaceX, reinvigorating space exploration. Palantir, integrating the world's data to save lives. There have, and always will be, these startups doing serious world-changing innovation. Are any of those actually startups anymore? SpaceX has over 2000 employees. Palanir has over 400. Tesla had it's IPO in 2010. They're just companies, they've all delivered products to market, and are(with the possible exception of Tesla, depending on their 2012 filings) making a profit.
