Gregory Benford tells about DARPA’s 100 Year Starship Symposium in “The First Hard Science Fiction Convention” —
Brother Jim and I had invited Steven Baxter, Elizabeth Bear, Geoffrey Landis, Robert Sawyer, Allen Steele, George Zebrowski, Joe Haldeman, Gerald Nordley, Charlie Stross and Vernor Vinge. We writers gave two panels moderated by Gay Haldeman before the ~1000 person crowd. Jim ran the biggest part of the tech program, propulsion. It was fun to see tech types recapitulate sf ideas – worldships, spacewarps, long lived societies, wormholes, intricacies of biology and aliens. They’re putting numbers on ideas we embodied in stories.
