After becoming an immortal digital being, Gabriel decides to spend millenia creating wormhole travel:&nbsp;"Without a purpose that spanned centuries he could only drift between interests &amp; aesthetics, friends &amp; lovers, triumphs &amp; disappointments. He could only live a life or two until there is no difference between his continued existence and his replacement by someone new."The book, alongide other's Egan related ones, touches on the quest for meaning in beings that can live forever.&nbsp;

Purpose for Immortals

Success has a thousand parents, but failure is an orphan. ﻿

By 2975 humanity has "speciated" into three distinct groupings:<ul><li>Fleshers: The traditional flesh&amp;blood humans, some in their original form others taking advantage of enhancements.&nbsp;</li><li>Gleisner robots: individual <a href="https://en.wikipedia.org/wiki/Software" target="_self">software</a>-based intelligences living in flesher-like bodies. They are mostly space explorers.&nbsp;</li><li>Citizens: simulated consciuousness individuals living in simulated digital worlds.&nbsp;</li></ul>

The evolution"humans"

Early on humans had fantasies about aliens arriving to conquer Earth and stealing their resources, never considering that a specie capable of making the journey would have probably get rid of the obsolete biological constraints.Conquering the Galaxy is what bacteria with spaceships would do - knowing no better, having no choice.When we get to explore space, our condition would be the opposite of that, we will have no end of choices. We would look to find civilizations who have faced the same decisions &amp; discovered what it means to inhabit the universe.

The myth of the conquering aliens

Humannity is divided into 3 groups: flashers, androids and digital human. All doing their thing and barely interacting. However, a neutron star collapses killing all flashers in an event that contradicts the current understanding of the cosmos. The event creates a panic among the other 2 human species, fearing a similar event can wipe them out too. The Diaspora consists of a collection of one thousand clones, deployed toward stars in all directions in the hope of gathering as much data as possible in order to understand the event.&nbsp;The adventrure keeps rotating back &amp; forth between different cloned instances of main characters, exploring alternate timelines and paralel universes.&nbsp;

Story of Diaspora (novel)

Since the Introdus in the twenty-first 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 bridgers 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 Yatima, a digital being grown from a mind seed, 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.

After the extinction of humans, how do you define humanity? Since the Introdus in the twenty-first century, humanity has reconfigured itself drastically. Most chose immortality, joining the polises to become conscious software.
