The list of people to whom I owe thanks for conversations that have shaped the ideas represented in this book is immense, and so my first expression of gratitude is simply to the field of sf studies itself, which has challenged me to become a better thinker and, even when it frustrated me, served as an important space for collaboration and refinement of ideas. Gerry Canavan, Grace Dillon, Paweł Frelik, David Higgins, Nalo Hopkinson, Roger Luckhurst, Colin Milburn, Hugh O’Connell, John Rieder, Steve Shaviro Rebekah Sheldon, and Taryne Taylor have been important interlocutors, and also sustained me through friendship and community alongside their astute scholarship. I owe thanks to my fellow editors at Science Fiction Studies, Istvan Csicsery-Ronay Jr., Art Evans, Joan Gordan, Veronica Hollinger, Carol McGuirk, and Lisa Swanstrom, and am grateful for their camaraderie and intellectual example.
I owe special thanks to my editor, Susan Buckley, for inviting me to work on this project and for helpful guidance throughout the process.
Finally, I thank my graduate students, past and present, in the Speculative Fictions and Cultures of Science Program. They inspire me with cutting-edge research in the field, work that embodies the range of things that the genre may yet become. This book reflects the possibilities for science fiction’s futures that I see daily as I have the privilege of working with them.
