description Diaspora Overview
Greg Egan's 1997 hard science fiction novel imagines a far future in which humanity exists in several forms, including biological people and software-based citizens. Many digital minds inhabit virtual communities called polises. The story begins with the creation of Yatima, a new digital person whose developing understanding offers an entry into societies organized around possibilities far removed from ordinary human experience. A catastrophic astronomical event drives a search for knowledge and survival beyond familiar environments.
Egan connects demanding mathematics and theoretical physics with questions about identity and the meaning of continued existence. The technical ideas are central to the action rather than decorative background. Diaspora suits readers willing to engage closely with scientific speculation and unusual forms of consciousness, particularly those interested in how intelligence might change when it no longer depends on a human body.
