Apparently Google is so dominant these days that you can have an entire branch of Google-specific futurism. The following is from Business 2.0:
What kind of company will Google become in the coming decades? Will it succumb to hubris and flame out like so many of its predecessors? Or will it grow into an omnipresent, omnipotent force–not just on Wall Street or the Web, but in society? We put the question to scientists, consultants, former Google employees, and tech visionaries like Ray Kurzweil and Stephen Wolfram.
As is usual in these things, the most useful reading is at the extremes — Google rules the universe, and Google flames out — but while the latter scenario is, historically speaking, the most likely, it is the least well crafted. While it could be privacy that does Google in, or rampant click fraud, it is most likely to be size, market saturation, and managerial incompetence. Why? Because that’s what does in most growth companies. It ain’t glamorous, but it’s true.
