My mates Gerry Canavan and Kim Stanley Robinson put this together. It has an essay by me--on the inevitable Avatar.
Listen to what Fred Jameson says about it:
“The book posits a fundamental opposition in the genre: the future-technological city (Utopia) versus the pastoral Arcadia: each believing the other one to be the true dystopia. Add to this our ecological crisis, and you have the situation all these SF essays confront in so topical and stimulating a way. This seems to me a truly timely and contemporary, innovative collection, breaking new ground for literature and perhaps for reality as well.”
