Actually, this - I believe - is the entire premise why we have no bubble this time around. It's because these companies are indeed on the bleeding edge of scientific discovery. The brightest minds in research work at these companies. The research and development that comes out of these companies, that create new open source work, and spawn out new markets in analysis, intelligence, economics - all of the work from these companies fuels growth for every other business out there who use any part of the technology stack to drive their business model. Just my 2 cents
