Book excerpt: Twelve visions of the future—by turns hilarious, frightening, and relevant—from new and established voices in science fiction. In this book, new and established voices in science fiction come together to offer original stories of the future. Ken Liu writes about a virtual currency that hijacks our empathy; Elizabeth Bear shows us a smart home tricked into kidnapping its owner; Clifford V. Johnson presents, in a graphic novella, the story of a computer scientist seeing a new side of the AIs she has invented; and J. M. Ledgard describes a 28,000-year-old AI who meditates on the nature of loneliness. We encounter metal-melting viruses, vegetable-based heart transplants, search-and-rescue drones, and semi-automated sailing ships. Sometimes hilarious, sometimes frightening, and always relevant, Twelve Tomorrows offers compelling visions of potential futures. Originally launched in 2011 by MIT Technology Review, the Twelve Tomorrows series explores the future implications of emerging technologies through the lens of fiction. Featuring a diverse collection of authors, characters, and stories rooted in contemporary real-world science, each volume in the series offers conceivable and inclusive stories of the future, celebrating and continuing the genre of “hard” science fiction pioneered by authors such as Isaac Asimov, Arthur C. Clarke, and Robert Heinlein. Twelve Tomorrows is the first volume of the series to be published in partnership with the MIT Press. Contributors Elizabeth Bear, SL Huang, Clifford V. Johnson, J. M.
