Google Peaking?

There is an interesting article over here at Silicon Alley Insider trying to predict when and why Google will cease to be the game changer in the Internet world. Central to the author's thesis is that once you are the very center of disruptive change, you stop being disruptive and are just doing what you're doing better than anyone else.

My suspicion is that Google's power will begin fraying at the edges as customers and advertisers realize that Google has too much power and too much information - but substantive change to its competitive position will not occur until a great alternative comes along.
