Imagining the history of the twenty-first century through its artifacts, from silent messaging systems to artificial worlds on asteroids. In the year 2082, a curator looks back at the twenty-first century, offering a history of the era through a series of objects and artifacts. He reminisces about the power of connectivity, which was reinforced by such technologies as silent messaging—wearable computers that relay subvocal communication; recalls the Fourth Great Awakening, when a regimen of pills could make someone virtuous; and notes disapprovingly the use of locked interrogation, which delivers “enhanced interrogation” simulations via virtual reality. The unnamed curator quotes from a self-help guide to making friends with “posthumans,” describes the establishment of artificial worlds on.
