This far-reaching anthology traces the path of the Singularity, an era when advances in technology will totally transform human reality. It travels to the alien far-future of H. G. Wells (Mind at the End of Its Tether), to the almost human near-future of Ray Kurzweil (The Singularity Is Near), from Elizabeth Bear's fusion of woman, machine, God, and shark (?The Inevitable Heat Death of the Universe"), to Isaac Asimov's evolution of ineffable logic (?The Last Question"). As intelligence both figuratively (and possibly literally) explodes, science-fiction authors and futurists have dared to peek over the edge of the event horizon. Join them there.
