I was hoping for an informative well-written article. Alas, I was to be disappointed. Ignoring the juvenile profanity and the condescending rhetoric, the author completely misdiagnoses the technology shift that will be the real game changer ... namely, the advances in memory architecture. Whether it's memristors or Xpoint 3D or some other architecture, data storage will be completely turned on its head over the next 10 years. The lumbering giants (who bring in 4 times more in net profit in a single quarter than Pure Storage garnered in its IPO) will have to be nimble in the future, but I wouldn't call them the 'walking dead' just yet.
The point of exactly how profitable the "walking dead" are is vastly underrated. The decision is between making giant profits now with low-risk VS miniscule profits but potentially large future profits with high-risk.
