Diaspora by Greg Egan

Synopsis: Behold the orphan.

Born into a world that is not a world.

A digital being grown from a mind seed, a genderless cybernetic citizen in a vast network of probes, satellites and servers knitting the Solar System into one scape, from the outer planets to the fiery surface of the Sun.

Since the Introdus in the 21st century, humanity has reconfigured itself drastically. Most chose immortality, joining the polises to become conscious software.

Others opted for gleisners: Disposable, renewable robotic bodies that remain in contact with the physical world of force and friction. Many of these have left the Solar System forever in fusion drive starships.

And there are the holdouts. The fleshers left behind in the muck and jungle of Earth — some devolved into dream-apes; others cavorting in the seas or the air; while the statics and bridges try to shape out a roughly human destiny.

But the complacency of the citizens is shattered when an unforeseen disaster ravages the fleshers, and reveals the possibility that the polises themselves might be at risk from bizarre astrophysical processes that seem to violate fundamental laws of nature. The Orphan joins a group of citizens and flesher refugees in a search for the knowledge that will guarantee their safety — a search that puts them on the trail of the ancient and elusive Transmuters, who have the power to reshape subatomic particles, and to cross into the macrocosmos, where the universe we know is nothing but a speck in the higher-dimensional vacuum.

Quite simply the boldest and most wildly speculative writer of his generation, Greg Egan has written a quantum Brave New World  for the century’s end — a masterful SF saga envisioning a time when not only humanity but “reality” itself will be but a memory.

It is a novel unlike anything you have ever read. Or even imagined.

Well written, engaging ‘hard’ sci fi is rare and it is even more rare to find novels as challenging and engaging as this one. This story of a distant future in which being posthuman becomes a necessity is mindbending as well as inspiring, with three alternatives explored: genetic, virtual and robotic. Best treated as a highly speculative extended thought experiment, for the most chilling effect I dare you to get the iBook and get Siri to read the first few pages aloud. – Matt Riddle from his list of 10 Great Books on Technology
