No, this isn't satire. Please check my other comment: https://news.ycombinator.com/item?id=16218591

There are always exceptions (like your containerization example), which can be attributed to serious tech players like Yahoo, Google and FB in South Bay. However holistically, SF has had much more unicorns and near unicorns. The contrast between SF and rest of the world has been more pronounced in recent year vs pre-2010 (except China of course - due to the growing economy and closed nature making it difficult for outside companies to operate).
