"This influential, yet controversial idea requires that the mixture of species on Earth at any moment acts as a collective organism that continuously (yet unwittingly) tunes Earth's atmospheric composition and climate to promote the presence of life... But I'd bet there are some dead Martians and Venusians who advanced the same theory about their own planets a billion years ago."

It will be good for us in the long run, and I mean there are six and a half billion people in this world. And it's great for 300 million to keep enjoying more and more property, but I think it's terrific if the remainder do. And I think if they can learn something from us in terms of our system, and I think they have, they are learning more about how to unleash the potential of their citizenry to turn out more goods and services that their citizens want or that we want, I think that's terrific.
