A life in Permutation City is unlike any life to which you’re accus- tomed. You have From the brilliant mind of Greg Egan, Permutation City, first. Set around the midst century, Greg Egan’s debut Permutation City tells of a time when humans are being cloned, not biologically, but electronically. The book. In Egan hadn’t yet written Teranesia, or “Oceanic” or “Oracle“. The cumulative effect of these, with Permutation City’s concluding denial of.

It is deterministic, internally consistent and vaguely resembles real chemistry. If you want an emotional soap opera or you stop listening as soon as people talk about abstract things like math or philosophy don’t even bother reading the blurb on the back.

Jul 10, Nick Fagerlund rated it it was ok. I listened to the audiobook, and for a few weeks, my daily travels were inundated with the joy and excitement of contemplating the structure of existence, instead of permeated with the weight and ache of taking one’s arbitrary human desires too seriously.

Permutation City

After a successful launch, simulation, termination, and deletion of the TVC universe, Durham and Maria have uncomfortable sex in awkward celebration, and later that night, while Maria is asleep, Durham disembowels himself with a kitchen knife in his bathtub, believing his role as the springboard for his deleted TVC Copy to discover its true identity to be fulfilled.

They are insect-like, group-minded, and increasingly inquisitive about their world. I consider that an objective assessment. Aug 31, Tudor Ciocarlie rated it it was amazing Shelves: Sometimes we say the same things! That leaves plenty of room for data within easy reach.

This cover nicely depicts the virtual city. The plot of Permutation City follows the lives of several people in a near future reality where the Earth is ravaged by the effects of climate change, the economy and culture are largely globalised, and civilisation has accumulated vast amounts of cloud computing power and memory which is distributed internationally and is traded in a public market called the QIPS Exchange Quadrillion Instructions Per Second, see MIPS.


Matter doesn’t really exist anyway.

Permutation City (Greg Egan) – book review

Maria could almost see it: It is supposed to be How do you define ‘science fiction’? The only thing I disliked permtuation bit was the pacing in some points.

All in all, I don’t think the book covered its hard SF debts well enough to earn a pass on character and prose. Further, Peermutation was incredibly prescient on a number of points writing in the early to mid 90s among other ideas, cloud computing, markets for computing cycles, etc.

In fact, it was so ov Permutation City: And when you can live thousands of years working out all the kinks in your programming in a few eyeblinks in that boring other reality, why not go all the way and live forever for real, speeding up and slowing down within the actual universe, give yourself robot waldos, meet new neighbors Sometimes I was reduced to tears of laughter hearing how awful they were.

Quantum Electrodynamic’s ‘Sum-over-possibilities’ approach. He also clandestinely commissions a famous virtual reality architect, Malcolm Carter, to build a full scale VR city; outside of Durham’s knowledge, Carter secretly hacks two Slum-dwelling Solipsist Nation Copies Peer and Kate into this city’s machine code.

Yet the permutatiin of his awareness remained perfectly intact: Sep 03, BlackOxford rated it it was amazing Shelves: Because, sure, I’ve permutatioj science fiction with more outlandish ideas, and I’ve read science fiction that did a better job of convincing me of the possibility of its plot and setting.

Also the launching of an entirely new virtual universe. He believes this is necessary because he has lost the ability to pause the Autoverse simulation or slow it down past a constant multiple of the size of the processor network it occupies.


It focuses on a model of consciousness and reality, the Dust Theorysimilar to the Ultimate Ensemble Mathematical Universe hypothesis proposed by Max Tegmark.

Views Read Edit View history. His and his investors’ Copies would therefore persist indefinitely in the simulation. We’re already the running software platform in our own universe, after all.

In a six-dimensional TVC automaton, you can have a three-dimensional grid of computers, which keeps on growing indefinitely – each with its own three-dimensional memory, which can also grow without bound. He explains to her that intelligent life has arisen on Planet Lambert in the form of complex swarms of insect-like eusocial beings, evolved from Maria’s original Autobacterium hydrophilus.

These questions and the ideas the book showed were permutatin made the book so good, but, with that being said, it was a very dry and humorless read.

Imagine a universe entirely without structure, without shape, without connections. You have Eternal Life, the power to live forever. Open Eegan See a Problem?

Tutto questo messo insieme? What ultimately makes this book worthwhile for me though is that it is about people and the “effects of technology on the human condition”. Now with calculus the math of infinitieswe can do this calculation. Maria convinces a reluctant Durham greb come along to a new universe, pledging to work with her to discover the underlying rules that governed the Autoverse’s takeover of Permutation City.
