Apple, FB and Instagram are capitalist-based companies that wish to maximize profit. People are narcissists and generate demand for narcissistic products, and are willing to pay and/or invest time on them. From a tech point of view, you can argue that a lot of these companies innovated in being able to scale their solutions to supply the "narcissistic demand" of billions of people in real-time. From a product point of view, you can argue that a lot of these companies managed to figure out the most comfortable and intuitive ways for people to express their narcissism. From an all market point of view, you can also argue that lots of non-tech companies also exist based on narcissism, e.g. cosmetics, fashion. If silicon valley's next bubble does burst, it will probably have nothing to do with narcissism, and more to do will investment speculators not learning their lesson the first time.
