American Constitution Needs To Be Upgraded?

According to Ruth Bader Ginsberg, an U.S. Supreme Court Chief Justice, the U.S. Constitution can no longer serve as a model for emergent and contemporary democracies:

 I would not look to the United States Constitution if I were drafting a constitution in the year 2012. 

Not only is this a sign that American prestige and power in the world of today is waning, but it also signals the continual displacement of the old by the new and is a poignant testament to the dynamism of change. Change is a process and things are always in flux. Let's bow to that.

What demoralizes me, however, is the language in which this history of change is being minted: It's the same old language of the Web and the market. Thus, for instance, a prominent legal scholar has attributed the decline of the American constitution's global influence to the following:

Nobody wants to copy Windows 3.1. 

The scholar is referring to the the availability of "newer" and "sexier" and more powerful operating systems in the Constitutional marketplace.
