With this I tend to agree: As humans we have reached maybe the top of our evolutionary track. We demonstrated that we are simply not able to build any sustainable society and that we are destroying the planet who gave us birth. But I disagree that: a superior form of intelligence will make the system stable.
One could also say we have reached the "end" of our evolutionary track. There are some who argue that human intelligence is an attribute that might just make us extinct. Daniel Quinn the author of Ishmael is one.
Watch YouTube videos of Al Bartlett's ideas. As a physicist he sees the problem in simple arithmetic. Too many people and the notion that more growth is the answer. More technology is not the answer. Human technology has been developing since before fire.
