On doit pouvoir ressentir un plaisir intellectuel à appréhender les constructions fantasmagoriques de Gregg Egan dans ce Matrix quantique, mais j'ai trouvé le livré déséquilibré et globalement franchement improbable, même si l'idée de départ est intéressante. De la science-fiction intelligente et documentée, peut-être un peu trop !

5.0 étoiles sur 5 Hard science fiction by a master of that genre, with his usual insights regarding the sociological implications 31 décembre 2016
Par Doug J. - Publié sur
Format: Format Kindle Achat vérifié
I am: a Greg Egan fan; a reader of only the hardest of the hard science fiction books; a computer science academic researcher; experienced in doing research on "AI" (the interpretation of which has evolved over the last four or so decades). So it is unsurprising that this book scratches my science fiction reading itch.

Despite my lack of qualification as a literary critic, this book seems to me to be somewhat weaker in style as a literary work than as a scientifically based hard science fiction speculation involving important sociological and morality issues.

On that basis, I strongly recommend reading the other reviews, some of which are very insightful, and will inform you about whether this book is for you or not.
4.0 étoiles sur 5 A solid addition to any hard sci-fi fan's library 27 avril 2017
Par Jerry - Publié sur
Format: Broché Achat vérifié
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 1994 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

5.0 étoiles sur 5 Important and challanging 12 juillet 2016
Par Robert Hills - Publié sur
Format: Broché Achat vérifié
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. "Hard SF" for the fans of "hard SF" is accurate but unfortunately may dissuade too mayny potential readers, just as calling ""Gone with the Wind" historical fiction is silly at best.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.

3.0 étoiles sur 5 A Mind-Blowing Journey 14 décembre 2016
Par Michael Rutherford - Publié sur
Format: Format Kindle Achat vérifié
Something about this novel was unexpectedly comforting. The idea of a "virtual world within a world" is very cozy to me, but Greg Egan contrasts utopian ideals with bleak realism. In the book, even though immortality can be achieved, humans are just as defective as they were before, and living forever births many new social issues. It's a powerful message that will likely be partially lost on many people, myself included, because of the highly technological and scientific nature of the text. Mr. Egan goes out of his way to make the book as accurate as possible, even if it's only theoretical, which is amazing, but it comes at the expense of understanding. The world he established is believable, plausible, and seems right around the corner. Ultimately, this is a fantastic novel, but it certainly puts the "Hard" in "Hard Science Fiction".

5.0 étoiles sur 5 Speculative sci-fi at its best 26 juillet 2014
Par Amazon Customer - Publié sur
Format: Format Kindle Achat vérifié
Very well written, speculative/philosophical sci-fi. 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.
