Also, here is an article in the New York Time titled: "The End of Ingenuity."
Here is a quote from it that I thought was pretty amazing considering the fact it's the New York Times.
"But in the larger sense, we really need to start thinking hard about how our societies — especially those that are already very rich — can maintain their social and political stability, and satisfy the aspirations of their citizens, when we can no longer count on endless economic growth."
There is a really good discussion talking about this article over at MetaFilter.
