I find it weird that people idolize businesspeople who basically just engage in ponzinomics.
They create businesses that don't make any money, often don't have any plans to ever make money, with the hope that they either get bought out by a BigCo or become public so that it becomes the index funds' problem.
It feels like this has been going on for about as long as Silicon Valley has been a thing, so maybe it actually is sustainable, but it sure feels like we are building our economy on a house of cards.
