Not the end of capitalism, don't be silly.  Capitalist economy in transition of course.  It isn't the number of firms on the public traded exchanges but the amount of market capitalization - which is higher at present by any measure than ever before.  There are some interesting consolidation dynamics taking place, for instance as exemplified by the likes of Amazon; and there is the problem of what old school analysts consider the blue sky over-cap of the tech giants but that might simply reflect the paradigmatic shift of a capitalist economy from one stage to another.  Don't jump out of the windows anyone.  It is a great future; invest, diversify, work and enjoy life and let time compound your wealth.
