This anthology unites twenty of today’s leading thinkers, writers, and visionaries—among them Cory Doctorow, Gregory Benford, Elizabeth Bear, Bruce Sterling, and Neal Stephenson—to contribute works of “techno-optimism” that challenge us to dream and do Big Stuff. Engaging, mind-bending, provocative, and imaginative, Hieroglyph offers a forward-thinking approach to the intersection of art and technology that has the power to change our world.
