The story follows , a man obsessed with achieving true, eternal immortality for these Copies, who are otherwise doomed to die when their host computer hardware inevitably fails. Core Concept: The "Dust Hypothesis"
Written in 1994, it portrays a highly realistic, terrifyingly plausible 2050.
Egan suggests that the mathematical data constituting a consciousness exists regardless of the order in which the calculations are performed. Even if a simulation is broken into pieces, scattered across time, and computed in a chaotic, non-continuous way ("dust"), the experience of that conscious self still occurs.

The novel's main intellectual driver is the "Dust Hypothesis." Egan challenges the notion that consciousness requires a continuous, physical, hardware-based simulation. The story follows , a man obsessed with
Permutation City (1994) Author: Greg Egan Genre: Hard SF / Post-Cyberpunk The Premise: Life as a Copy
Permutation City explores a near-future where human consciousness can be scanned and simulated in digital form, creating "Copies." These Copies are not mere recordings; they are sentient, subjective, and indistinguishable from their physical, flesh-and-blood originals. Even if a simulation is broken into pieces,
It is considered one of the ultimate explorations of digital consciousness, merging complex physics and computer science.
