Ebenfalls Campbell Award heißt der John W. Campbell Best New Writer Award. , Greg Egan, Permutation City, Cybercity. , – kein Preis vergeben –. Greg Egan (* August in Perth, Australien) ist ein australischer Fantasy- und Permutation City, in der Kategorie Roman für Cyber City. mp3albums.nu: Permutation City () by Greg Egan and a great selection of similar New, Used and Collectible Books available now at great. And now that it had reached that stage, it seemed like the obvious thing to do. Alas, as I wrote in DiasporaGreg Egan is not for everyone. How could I improve on a scheme like that? This book came into Diamonds Slots Review & Free Instant Play Game life at a pretty good time. Permutation city the very long-winded technical details of what was going on went completely over my head. What he doesn't realize is that the intelligence of Planet Lamberti has exceeded the complexity of their own world, and that Lamberti has ceased to be defined as their simulation- Tennis live ergebnisse City is now defined in terms of Autoverse physics rather than the other casino bonusse ohne einzahlung around. At the end of Part 1, Durham reveals his true intentions to Maria: In this way, Egan attempts to deconstruct not only some standard notions of self, memory, and mortality, but also of physical reality. This time we are in a world where Virtual Reality VR is nearly perfected and it is possible to download people's brains in to computers. And although some tropical island bonuscode the autoverse chemistry was way beyond me, the whole dust theory and VR propositions were not easy at first, for sure very comprehensible. These spiritual bits can become quite unruly in their condition of fragmented isolation. Permutation city tanto transmigrador de almas Hypothetical light rays were being traced backwards from individual rod and cone cells on his simulated retinas, and projected out into the virtual environment fußball.de 3.liga determine exactly what needed to be computed:

The characters are two dimensional exposition machines, the prose is largely utilitarian, and even the plot is pretty flimsy. Further, the conceit at the heart of the novel and the fulcrum for all of the action is a theory the so-called "dust theory" that is ridiculous balderdash and, if taken seriously, basically an excuse for moral heinousness.

However, the book is also an amazingly thoughtful rumination on the philosophical and psychological issues that w This is a tough book to evaluate.

However, the book is also an amazingly thoughtful rumination on the philosophical and psychological issues that would arise with translating our consciousness onto a computer substrate.

Egan evaluates the challenges that would arise if you were able to copy yourself, personality, memories, and all, into a virtual world in a computer, and how that copy would interact with your original meat version, how the copy would adapt to the limits of its new environment, and what the legal and moral obligations would be in interacting with such copies.

It's like a really interesting essay on the Singularity with a fine lace of silly plot frippery around the edges. Further, Egan 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.

This is probably not my first choice for books about mind uploading, but it's a pretty interesting take and worth the read for anyone interested in the subject.

Also, it totally affected my dreams the whole time I was reading it, which is always a good sign. Sci fi story about creation and immortality and computer virtual reality.

Don't want to give away too much but gives a plausible vision to the idea of immortality through being uploaded and questions the boundaries between the virtually created and their creators.

Very deep story touch on many philosophical themes. Definitely very good sci fi. May 20, Roy rated it did not like it. Im not the biggest hard scifi fan but thought I'd give this a go.

I have loved most of Egans short stories. However this was too much Science for me and not enough plot. Some parts just dragged a little too much for me.

This is one of those books that stayed with me long after I put my kindle down. The ideas Egan shows are so big, so compelling that you cannot help but try and put yourself on the shoes of some of the characters.

If both copy and he original can coexist, the death of the original matters? Were we the same person anyways? Or am I only giving Whoa!

Also, how long can someone change himself until his identity is lost? These questions and the ideas the book showed were what made the book so good, but, with that being said, it was a very dry and humorless read.

I enjoyed and cared for the characters, specially Maria and Peer. And although some of the autoverse chemistry was way beyond me, the whole dust theory and VR propositions were not easy at first, for sure very comprehensible.

The only thing I disliked a bit was the pacing in some points. There were a few description heavy parts that I could do without. But overall, it was a great read!

Dec 03, Akiva rated it it was ok. I have this awesome string of random bits that I'm hiding in my pocket.

It is a magical fairy land with dragons and wizards and lots of attractive princesses that need saving. What do you mean that's just pocket lint?

I can interpret it however I want. There's so much pocket lint in the world surely some of it is actually Narnia. In my pocket lint universe I am an immortal god!

What do you mean pocket lint immortal god Me has nothing to do with the Me that you've known for the last three hundred pages?

We've got the same name. We look the same. Sometimes we say the same things! The premise of this book made no sense. That's fine in the abstract. There are plenty of books worth reading that make no sense - everything I've read by Murakami for example.

But this is a Greg Egan book, so the real point of it is the idea, which as I may have mentioned, makes no sense. Go read his collection Axiomatic instead.

This is the second Greg Egan novel I've read, after Distress. Both books follow the same rough template: Both of these books are very pure instances of conceptual science fiction; the philosophical and scientific ideas are the meat of the book, not just convenient setup for the plot.

Permutation City is actually a lot "purer" than Distress in this sense -- pure to the point that I had a hard time maintaining interest. At least Distress had something like a plot, and something like a central conflict, and something like a sense of suspense.

That wasn't enough for me, not I think out of any lack of interest in science and philosophy, but because the arguments Egan presents for his ideas aren't very convincing.

Unfortunately, I don't think they could be without devoting much more space to them, which would make the book so "pure" it would almost be de facto nonfiction.

For an example of the effect I imagine this book is meant to have upon its reader, take a look at this wonderful sentence from Cosma Shalizi's review: Dick channeling Marvin Minsky channeling Bertrand Russell channeling Leibniz with a few hundred micrograms of LSD tossed in at some point in the chain imagine a novel which can use the phrase "the economy of ontology," not just without grinning or blushing, but perfectly convincingly and you'll have some idea of what Permutation City is like.

Note that three of the four writers Shalizi mentions are non-fiction writers, and the one exception Dick is a highly conceptual SF writer. But of course Permutation City is a work of fiction, and it's not going to be able to devote long stretches of text to clarifying small points or handling counterarguments, the way Russell or Leibniz might.

If the central idea starts to seem shaky to you, you're pretty much lost, because Egan spends most of his time elaborating it rather than justifying -- the former is much easier to integrate with fiction than the latter, after all.

Which is pretty much what happened to me. I guess the concepts in Permutation City aren't really much more implausible than those in Distress, but at least the concepts in Distress just kind of appeared from offstage with no pretext of justification.

In Permutation City a lot of the story is about people discovering and exploring the concepts -- they don't just get dumped on the reader from nowhere -- which means it runs into problems when it becomes clear that Egan's justifications aren't really philosophy-grade, nonfiction-grade justifications.

I can believe pretty much anything if the author tells me to, but the characters can't, and what is presented as a fascinating story of discovery seemed more to me like people coming up with absurd guesses that happened to be confirmed because the author arranged it that way.

So when Durham gets the idea from the dust theory from the fact that his consciousness can connect states separated in space and time, why doesn't he note that in every case the states are causally connected, and thus that the "connections" aren't necessarily miraculous or metaphysical at all -- there's always a purely physical connection, specified by the computers simulating him, between the states?

Of course Durham's idea solidifies when the world keeps generating convenient "explanations" whenever he gets shut off, which is harder evidence, I guess, but seems to run into anthropic principle worries isn't it a priori likely that even if most Copies just become non-conscious when shut off, there might still be some long "chains" like Durham?

No deja de ser un buen ejemplo de modelado de modelo de la realidad. Pocos autores conozco que se atrevan a ir tan lejos.

Bueno, conozco muchos que no escriben novela que lo hacen pero en novela conozco pocos. Un tanto transmigrador de almas Un problema de este autor es que no sabe huir de las explicaciones de lo que desconoce.

Azar y Caos de Ruelle es del Tuvo tiempo para documentarse. Otro problema gordo es que los sujetos y algunas personas en la novela tienen personalidades inexistentes, aleatorias No me gustan los personajes de este hombre.

Pero las novelas de este hombre no van de personajes. Al menos no ha tirado de valores morales universales e inmanentes No lo leas buscando Hard SayFay porque hoy por hoy esta novela contiene inexactitudes importantes.

Tampoco busques transhumanismo porque Greguito no se maneja bien con personas, sociedades Atiborra al lector de datos que no significan nada como un anuncio de detergente para lavadoras Pero no te fijes mucho.

Por cierto, varias de las ideas desarrolladas me hicieron pensar en la serie Westworld. Il processo che li genera? Il rapporto tra i numeri? Tutto questo messo insieme?

Scenari cyber degni di Gibson e soci, scenografie e paesaggi mastodontici che ricordano un po' Ian M. Forse troppo complesso, troppo matematico, soprattutto: Egan, del resto, ha una formazione da programmatore, che incide molto sul romanzo.

Affascinante, certo, estremamente visionario, e anticipatorio soprattutto questo: Che personalmente non possiedo del tutto.

In ogni caso, una pietra miliare, senza dubbio. Nov 08, David rated it really liked it Shelves: Egan writes sci-fi, heavy on the sci.

The protagonists of Permutation City are software humans, scanned from fleshly originals, virtually immortal, and fated to craft a purpose for themselves in a world of infinite flexibility.

Jun 30, Alex Chaffee rated it really liked it. This book has all the stuff I was thinking about in the early s -- artificial life, genetic algorithms, cellular automata, philosophy of consciousness, virtual reality, neurochemistry, brain simulation -- all woven together into a premise that is absurd but with enough actual computer science and inside jokes to make it mind-blowingly plausible.

Not a lot of action, but fun -- if you can follow the details. Aug 31, Tudor Ciocarlie rated it it was amazing Shelves: Fantastic book, very well written, with great characters and full of fabulous ideas.

But what's really incredible is that this is an almost 20 years old near future hard SF novel that doesn't feel outdated at all.

Una vez hecho ese acto de fe ya puedes pasar a recrearte con la originalidad del autor en lo que se refiere a posibles futuros. Es un autor que tiene algo que me engancha.

Una lectura compleja pero que engancha, si lo lees sin darle mil vueltas a las teorias que a veces cuenta se disfruta y mucho. Jul 10, Nick Fagerlund rated it it was ok.

This one came up when Schwern and I were poking around the Wikipedia articles about Conway's Game of Life, and I was like, "You know what, it's been way too long since I just said 'fuck everything' and downed a whole book of potentially dubious quality in a single slurp.

The plot didn't lock together very well, This one came up when Schwern and I were poking around the Wikipedia articles about Conway's Game of Life, and I was like, "You know what, it's been way too long since I just said 'fuck everything' and downed a whole book of potentially dubious quality in a single slurp.

The plot didn't lock together very well, and I consider the main construct in the story to be uncool sorcery.

All in all, I don't think the book covered its hard SF debts well enough to earn a pass on character and prose.

Also, while Egan made some interesting steps in considering how consciousness changes when it can self-modify beyond the tolerances of electric meat, I don't think he really took it far enough.

Still, there were some parts to like: Nov 26, Bria rated it it was amazing Recommends it for: This book came into my life at a pretty good time.

Being reminded how your personal self-indulgent bullshit just really doesn't rate that highly was just what I needed this spring.

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.

Even though I never quite forget about cellular automata - they This book came into my life at a pretty good time.

Even though I never quite forget about cellular automata - they're there, just below my surface, constantly waiting to burst through - this book made me want to re-attempt reading A New Kind of Science.

I remembered when I tried to read it a few years ago until I got a full-time job and suddenly didn't have the hours and hours a day it took to really, truly appreciate what a genius Stephen Wolfram is , and I got stuck on the idea that somehow all the information of a function is contained in its initial conditions.

Its entire existence is contained in it from the beginning, but most of it is only latent until time unfolds, or another dimension is added.

I couldn't seem to get anywhere with this thought, but it rung around in my head for ages. And so I don't know if I misunderstood what Elysium was and how it was built, but the way I interpreted it, perhaps completely missing the actual explanation, was that Durham actually just set up the software and input for this universe, and once it was proven to be mathematically consistent then that was all that was required for it to exist.

So that got locked up with my previous thoughts, and I have nothing insightful to say about them except that it's rather exciting to contemplate.

Es realmente un rompedor de cocos de alto nivel. Pero no ha sido mi caso. First published in , it reads as relevant today as any modern day tech-fi, if not perhaps more so, encompassing a deep cogitation of reality and it's endless boundaries elevated by technology and re-rationalizing what it means to simply 'be'.

The story is multifaceted, taking the reader on a journey through the possibilities of alternate life, and exploring the inventive use of sophisticated technology, while also delving deep into the human psyche to question it's very existence in both biological and artificial terms.

Review first appeared on my blog: Greg Egan specialises in hard science fiction stories with mathematical and quantum ontology themes, including the nature of consciousness.

Other themes include genetics, simulated reality, posthumanism, mind transfer, sexuality, artificial intelligence, and the superiority of rational naturalism over religion.

He is a Hugo Award winner and has been shortlisted for the Hugos three other times , an Greg Egan specialises in hard science fiction stories with mathematical and quantum ontology themes, including the nature of consciousness.

Some of his earlier short stories feature strong elements of supernatural horror, while due to his more popular science fiction he is known within the genre for his tendency to deal with complex and highly technical material including inventive new physics and epistemology in an unapologetically thorough manner.

Egan is a famously reclusive author when it comes to public appearances, he doesn't attend science fiction conventions, doesn't sign books and there are no photos available of him on the web.

Other books in the series. Subjective Cosmology 3 books. Books by Greg Egan. Permutation City is a science fiction novel by Greg Egan that explores many concepts, including quantum ontology , via various philosophical aspects of artificial life and simulated reality.

It won the John W. Campbell Award for the best science-fiction novel of the year in and was nominated for the Philip K. Dick Award that same year.

The novel was also cited in a Scientific American article on multiverses by Max Tegmark. Permutation City deals with a question common in cyberpunk and postcyberpunk works: More specifically, Permutation City focuses on exploring one possible model of consciousness and reality, the Logic of the Dust Theory of reality, or simply Dust Theory , similar to the Ultimate Ensemble Mathematical Universe hypothesis proposed by Max Tegmark.

Like some other works of contemporary science fiction, it begins with the assumption that human consciousness is Turing computable: Specifically, the book deals with some possible consequences of human consciousness being amenable to mathematical manipulation, as well as some possible consequences of simulated realities.

In this way, Egan attempts to deconstruct not only some standard notions of self, memory, and mortality, but also of physical reality. Over the course of the story, Egan gradually elaborates the Logic of the Dust Theory of reality, the implications of which form the premise for much of the story's intrigue.

The story explores these ideas through a variety of avenues. One is that of the Autoverse , an artificial life simulator ultimately based on a cellular automaton complex enough to represent the substratum of an artificial chemistry.

The Autoverse is a deterministic chemistry set, internally consistent and vaguely resembling real chemistry, but with only thirty-two elements and no nuclear analogue.

In the novel, tiny environments, simulated in the Autoverse and filled with small populations of a simple, designed lifeform, Autobacterium lamberti , are maintained by a dwindling community of enthusiasts obsessed with getting A.

Another venue for these explorations is VR, virtual realities making extensive use of patchwork heuristics to simulate, crudely , completely immersive and convincing physical environments, albeit at a maximum of seventeen times slower than "real" time, the limit to the optical crystal computing technology used at the time of the story.

Larger VR environments, covering a greater internal volume in greater detail, are cost prohibitive even though VR worlds are computed selectively for inhabitants, reducing redundancy and extraneous objects and places to the minimum details required to provide a convincing experience to those inhabitants, e.

Within the story, " Copies ", digital renderings of human brains with complete subjective consciousness, the technical descendants of ever more comprehensive medical simulations, live within VR environments after a process of "scanning".

Copies are the only objects within VR environments that are completely mathematically internally consistent, everything else being the product of varying levels of generalisation, lossy compression , and hashing at all times.

Copies form the conceptual spine of the story, and much of the plot deals directly with the "lived" experience of Copies, most of whom are the survivors of wealthy billionaires suffering terminal illnesses or fatal accidents, who spend their existences in VR worlds of their creating, usually maintained by trust funds which independently own and operate large computing resources for their sakes, separated physically and economically from most of the rest of the world's computing power, which is privatised as a fungible commodity.

In this way, Egan also deals with the socioeconomic realities of life as a Copy the global economy of the novel is in recession and Copies often lose their vital assets , many of the less wealthy of whom live in " the Slums ", a euphemism for the state of being bounced around the globe to the cheapest physical computing available at any given time in order to save money.

Many such lower-and-middle-class Copies exist at considerable "slowdown" relative to "real" time or even optimum Copy time, in order to save further money by allowing themselves to be computed momentarily from place to place and saved in suspension for cheap in the meantime.

Through this, the concept of solipsism is examined prominently, with many lower-and-middle-class Copies attending social functions called Slow Clubs, where socialising Copies agree to synchronise with the slowest person present.

To give a trivial example, instead of storing and manipulating all the relevant quantities as binary floating-point numbers, they could be encoded in a variety of different schemes.

Moving beyond that, the way in which the representation of the data reflected the three-dimensional layout of the physical objects being modelled could be obfuscated in various ways.

Given that some of the characters in the novel take the Dust Theory seriously, why should they care whether or not they achieve any of their specific goals?

Surely the same total set of events must happen to versions of them, regardless? I believe human nature is such that people would still act as they did in the novel.

Obviously some people, faced with this idea, would become passive. I chose the more interesting story. Actually, it could be argued that absolutely any set of experiences should be possible according to the Dust Theory, including this one.

Further Egan novels which deal with these issues from various other perspectives include Diaspora and Schild's Ladder. 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 the most commonly used denomination of currency is the ecu, from the word ecumen , a Greek root meaning 'the inhabited world' , and civilisation has accumulated vast amounts of ubiquitous computing power and memory which is distributed internationally and is traded in a public market called the QIPS Exchange QIPS from MIPS , where the Q is Quadrillions.

Most importantly, from the perspective of the story, this great computing capacity is used to construct physiological models of patients for medical purposes, reducing the need for actual medical experimentation and enabling personalised medical treatments, but also enabling the creation of Copies, whole brain emulations of "scanned" humans which are detailed enough to allow for subjective conscious experience on the part of the emulation.

Although not yet in widespread usage, scanning has become safe enough and common enough to allow for a subset of wealthy or dedicated humans to afford to create backups of themselves, generally with the intention of surviving the biological deaths of their bodies.

A minority of Copies exist, though they are largely perceived with some justification as being a collection of the thanatophobic eccentric rich.

Copies do not yet possess human rights under the laws of any nation or international body, although a subgroup of the wealthiest Copies, those still involved with their own estates or businesses, finance a powerful lobby and public relations effort to advance the Copy rights cause.

To this effect, the legal status of Copies is viewed as somewhat farcical even by sceptics of the cause, and many expect full Copy rights to be granted in Europe within two decades.

The plotline travels back and forth between the years of and , and deals with events surrounding the life of a Sydney man named Paul Durham, who is obsessed with experimenting on Copies of himself because he believes Copies of himself should be more willing to undergo experimentation.

In the latter time frame, Durham is revealed to be, apparently, a con artist of some type, who travels around the world visiting rich Copies and offering them prime real estate in some sort of advanced supercomputer which, according to his pitch, will never be shut down and will be powerful enough to support any number of Copies in VR environments of their own designing at no slowdown whatsoever, no matter how preposterously opulent those environments might be.

He pitches this concept to the Copies, predicated upon the prediction that the Copy rights movement might run into resistance due to devastating climate change.

As the world undergoes increasingly extreme and erratic weather, a variety of international bodies, especially the Association of Southeast Asian Nations , which has been particularly hard-hit by tropical storms, have proposed projects to use their vast computing resources to attempt to intervene, utilising chaotic effects to their advantage, in global weather patterns with such precision as to minimise weather-related destruction while also minimising the scale of the efforts necessary to do so.

Durham predicts this will clash with the spread of Copy rights, as both Copies and weather simulations will demand increasing QIPS Exchange shares in the future.

All that each Copy must do is to make the laughably small investment of two million ecus in order to bring Durham's fantasy computer into existence.

As part of his plot, Durham hires Maria Deluca, a nearly destitute Autoverse enthusiast, recently mildly famous for developing a variety of A.

Since no such computer exists, Durham attempts to convince Maria that he is a wealthy Autoverse enthusiast interested in her evolvability results and looking for a proof of concept for a much larger system.

He also clandestinely commissions a famous virtual reality architect, Malcolm Carter, to build a full scale, high resolution VR city, Permutation City, the largest VR environment ever conceived, complete with reactive crowds and a staggering variety of full scale, high resolution scenic views.

As computer fraud investigators begin to close in on Durham's scheme, Maria becomes implicated and is pressed into covertly gathering evidence in order to incriminate Durham; however, she comes to doubt her commitments as she learns more about Durham himself, including his time spent in psychiatric care and his callous experimentation on his own Copies, as well as his assiduously reticent Copy backers.

Meanwhile, two Slum-dwelling Solipsist Nation Copies, Peer and Kate, explore their post-human existences as well as their strained but loving relationship, until Kate's long-time friend Malcolm Carter offers to secretly hack them both, along with any moderately-sized software packages they wish, into Permutation City's machine code , guaranteeing them a place in the city were it ever to run, but permanently debarring them from manipulating the city's implementation for fear of being deleted as extraneous cruft by automated software.

At the end of Part 1, Durham reveals his true intentions to Maria: He hoped that by his "dust theory", the simulation would subjectively persist independently without computer time, cut off from the known universe.

His and his investors' copies would live forever in the simulation, and since the space of the simulation was made of self-reproducing cellular-automata computer processors, the simulation would not possess a mere finite number of states and the passengers wouldn't grow bored.

Just reading the back flap of this book doesn't even really begin to describe the depth of the concepts presented in this story.

While the material subjects in Permutation City are firmly planted in sci-fi, it also puts concepts such as what it means to "be" human both objectively and subjectively at the forefront.

Whether you are an ardent fan of computer science, biology, physics, or even philosophy, this book will elicit some kind of respect from you for its depth in those regards.

This book does lean heavily into both hard science and fiction, but quite honestly it takes the concepts so far that that distinctions between the two are trivial.

What this book ISN'T is a flashy science fiction romp with action and adrenaline for just for the sake of excitement. What we DO have is a deeply thought provoking series of events and perspectives that challenge how evolving technology can redefine or completely do away with our current concepts of humanity.

My only real cons are that Greg goes to such lengths to explain and take you to each of his thought points and conclusions, that the actual "story" is relatively light.

Now, if you enjoy staying in those thoughts and sort of letting them gestate, this won't be much of a problem.

If however, these thoughts don't resonate with you, you might find yourself waiting for the next "thing" to happen. Sort of on the other end of that, I felt that the conclusion of the book was a bit hasty.

When considering the effort that went into making sure that the reader has bought and understood the rules of the world, the end felt a tad rushed and unearned.

It's not to say that it's bad by any means, it just felt as if SOMETHING that fit a more typical sci fi ending had to happen just for the sake of it, rather than the story logically leading there.

The fact that this book was written in blew my mind, as many of the technologies mentioned seem like logical progressions of things that have only become common in the past 10 or so years, so the foresight alone is incredible.

All in all this book is a must read for any hard science fiction fan. While not perfect, enough love and attention clearly went into it to add it to your collection.

Greg Egan is an important writer in the tradition of Azimov, Verne and Wells. Like them, he explores the feasable technologigies of his era and expands their scope and implications for individuals and civilization.

Permutation City addresses immortatality, cloning and the utility of life in unique ways and in depth. Simly using the terms science fiction, ethical exploration or fantasy-allegory to catagorize this book and his output in general is both difficult and misleading.

Try this novel or sone of his short stories and decide: You may become addicted to him. This book and this author are one of my most frequent recommendations to my friends, especially millenial I am a geezer.

But not to all: Enjoying technologyand both knowing and enjoying learning about scientific concepts is critical.

High school physics or computer science and reading about current events in the science pages of, say, The New York Times is enough.

So too, if you enjoyed reading Carl Sagan's or Stephen Hawking's popular books then you are in the potential audience.

Kindle Edition Verified Purchase. I wanted to like this book. I gave it a chance. The concepts are interesting, and the setup was fine in the first half, then it fell flat.

It's very rare for me to not finish a book, so this was a rare dud from a decent author. I don't feel like writing a long review, but all of Greg Egan's works will make you think.

Some people find Egan's books to be hard reads, and indeed the author has even suggested that people take notes when reading some of his works.

This is probably the best book he's written IMHO. The premise of this is mind-blowing, and without offering spoilers, this is an entirely new twist on first-contact with a sentient species, among many other concepts and Egan writes so well about virtual reality, you end up hoping that if we ever achieve this level of VR, that his works will be used as a guidebook to implementation.

It's also an exploration of what consciousness may mean. Some say Egan doesn't develop his characters very well. And I somewhat agree. But he uses his characters more to help illustrate the ideas in his books than to be the primary focus.

It helps to have a technical background and basic understanding of computer science IMHO to fully appreciate this book. You also probably won't get a full appreciation for all of the ideas without rereading it a couple of times.
