5.0�toiles sur 5 Shockingly Good, Mai 8 2002

Par	Justin "E" (Seattle, WA USA) - Voir tous mes commentaires

This is perhaps the finest work of Computer Science based Science Fiction ever written. The most stunning thing here is that Greg Egan actually knows what he's talking about, and isn't afraid to stick to it, in exactly the way that so many "cyber" writers... don't. He actually understands recursion and virtualization, not just throwing words out to sound cool. He doesn't retreat into literary silliness or ridiculous anthropomorphic characterization in a feeble attempt to be some sort of artsy novelist. He keeps it believable, and extremely good.

This is the book I would have written, if I had time (and ability!) to write a novel about recursion and artificial life.

5.0�toiles sur 5 Mind Boggling, Janv. 25 2002

Par	Christopher Palmer "CMPalmer" (Huntsville, AL USA) - Voir tous mes commentaires (REAL NAME)

I'd have to rate this book as one of my all-time favorite SF books. I still freak out a bit if I think too hard about his dust hypothesis.

The best thing about this book is that I read it soon after I had read "The Minds I", a collection of essays about AI and human consciousnes. I suspect that Egan has read the same book, since many of the concepts of Permutation City are based on the thought experiements in The Minds I. This is not to say that Egan's book is not original, as the title suggests, the book is a riff or fugue on a number of concepts related to identity and consciousness.

Most of his wild extrapolations follow perfect logic if you accept the basic premise that a conscious software entity can be created. The idea that, if such an entity exists, maintaining the software state while shutting down the program, then restarting it later from the same state would be experienced by the entity as instantaneous, then following that a succession of these saved states in any chronological order should be perceived as the same experience is mind bending.

Amazon should bundle Permutation City and The Mind's I (and maybe Goedel, Escher, Bach) -- they make a great matched set.

5.0�toiles sur 5 Egan's cusp book, Janv. 4 2002

Par	Gordon Rios (Palo Alto, CA United States) - Voir tous mes commentaires

One of his last books that maintains some accessibility and entertainment value to balance off his increasingly abstract theses. After this, his books are quite difficult but this one is a lot of fun -- especially for CS people. Be warned however that it's definitely *hard* sf....

An excelent book. What would happen if you could be downloaded to a mainframe? And if your virtual self creates a virtual world that in time creates self consciounness?. Read more
