I really disagree with the idea this article is pushing "greens" are "downwingers" who are inherently opposed to technology. That can be true, but not as a general rule.
A lot of people who think about the future both are very optimistic about the possibilities of new and developing technology, and are concerned about resource depletion and other environmental issues. In fact, the two are often linked; a lot of people support pushing exponential growth in technology because they think the current course of our industrial civilization is unsustainable unless we move to a higher technological level then, say, burning coal to make electricity.
This is a great article at Aeon magazine. The author argues that the new ideological dichotomy is going to be between people who have great faith in technology and human innovation (Up) and the people who believe that humans are much more tied to their biology and the Earth (Down).
LW of course is a very Up community.
