Disch traces Sci-Fi's phenomenal growth from the supernatural tales of Edgar Allen Poe to the utopian dreams and technological nightmares of H.G. Wells and Jules Verne, to today when it has become a multi-billion dollar global entertainment industry. While he highlights the genre's predictive successes, he emphasises its cultural role as both a lens and a medium for the very rapid changes driven by modern technology. Disch traces sci-fi's role in all aspects of modern life and explains how it has become a cultural battlefield even helping us to adjust to new social realities. But Disch is also highly critical of the genre and sees its darker expression in the appearance of suicidal UFO cults. Behind the spaceships and aliens, Disch reveals the blueprints of the dizzying postmodern future we have already begun to inhabit.
