I skimmed this article 3 times...Sorry, was there any actual substance to this link-baity headline, other than "Mainframes were big, now they're not and PCs were big, now they are not, ergo, Google is big, and someday they will not be"?
The OP provides little to no hypothesis on what will takeover Google...more "human" content, a la Buzzfeed? Seriously?? And then the OP goes on to dismiss all of Google's next-gen research (self-driving cars, Google Glass, etc) with a conclusion akin "Well Microsoft Research sucked so Google will to".
The OP is link-bait wankery at its worst. I'm sorry to even have spent 15 minutes trying to interpret it.
