Presenting the post-human future in its wildest science-fictional imaginings and intriguing speculations, this far-reaching anthology of fiction and non-fiction traces the path of the Singularity, an era when advances in technology totally transform human reality. The featured stories and essays travel from the alien far-future of H. G. Wells and the almost-human, near future of Ray Kurzweil to Elizabeth Bear's fusion of woman, machine, God, and shark and Isaac Asimov's evolution of ineffable logic. Daring to peek over the edge of the event horizon as intelligence both figuratively and literally explodes, this collection also includes pieces by Nick Bostrom, Cory Doctorow, Robert Reed, Justina Robson, Charles Stross, Vernor Vinge, and more.
