Permutation City Reviews
If you're looking for Sci-Fi that injects new ideas and concepts into litterature and has a delightful reminiscence of Gibson, this will be for you.Very interesting book if you succeed in not getting lost as some parts are a little hard to follow. But beware, I tried lending the book to some friends who don't seem to be geeky enough to enjoy it. A pity...
Gehirnyoga - nicht mehr und nicht weniger. Als Kurzgeschichte ok. Mehr aber auch nicht. Ich habe mich nach den ersten Kapiteln nur noch gelangweilt.
Greg Egan is an ideas man par excellance! If the first few pages don't scare you, you haven't cranked up your sense of wonder anywhere *near* enough. The premise is fascinating; the super-rich can take virtual copies of themselves into cyberspace and still influence the real world. Us mere mortals cannot afford the supercomputer power needed...or is there another way? Greg is best in short stories and needs a while to tie his plot together; the wait is well worth it. His work is at least as good for the nineties as Asimov's for the fifties, Niven's for the seventies or Brin's for the eighties; I haven't come across anyone better in his genre. Enjoy! Also highly recommended: Axiomatic - surely one of the best speculative collections ever.
Best SciFi around, right now.This book and author richly deserve the praise that it has been given. It takes on a new level of significance (as do most the author's other major SciFi works) when the ideas within them are pursued. For example, perform web searches on the topics: "Information mechanics", "Edward Fredkin" "Digital Physics", "Quantum Information Theory", "Information Theory" and other combinations of these terms. You will find a wealth of interesting web pages confirming that the ideas in this book are the subject of ongoing research. When considered alongside the ideas in the author's book "Diaspora" and the writings of Hans Moravec the possibilities are endless.
The best science fiction isn't about science, it uses actual or potential developments in science in order to examine ourselves.Greg Egan's writing is among 'the best science fiction'. This book might appeal to techies who are just interested in the computer technology, but what it is really asking, like many of Egan's stories, is 'what does it mean to be human?'. He doesn't answer the question (how could he?), but he gives the reader more than enough to think about.Greg Egan's work is so far beyond the work of most dull mainstream (mostly US) SF authors, it is just ludicrous. Drop your Orson Scott Card, your Larry Niven - all your triumpahalist military SF garbage - and pick up Egan. You might learn something.
I already read "Diaspora" from the same author. This book basically contains the same idea, to be scanned and live in a virtual reality, but where the so called Introdus in "Diaspora" leads to a very abstract and utopian new form of living, "Permutation City" has a lot to say about the feelings and motivations of people to be scanned or not.On the other hand, the final threat to the universe is much more abstract in this book, but nonetheless very real to the protagonists.What really overwhelmed me was the unique idea of turning abstract, platonic concepts like Universal Turing Machines and cellular automatons into "real" and usable technology. This is truly a crazy idea, but Greg Egan manages to bring up some good arguments for it.The number of open questions that arise from this idea are numerous: Ethical questions about the rights of a simulated intelligence, philosophical questions about the reality of a mere idea and about reality itself, theological questions about heaven and hell.And Greg Egan manages to put all of this together in a thrilling story that runs on different levels.Read this book if you like hard SF! ;-)
This was an enjoyable enough read, I suppose, and it certainly contains some cool ideas (e.g. the concept of a cellular automaton rich enough to support a simple biochemistry). However, the bulk of the plot hinges on a deus ex machina that I found impossible to swallow, and this tainted my enjoyment of the book henceforth. Also, the characters were totally flat, not that this is unusual in "hard" SF.
What a delight to find this gem in a pile of used paperbacks we inherited! This is one of the best works I've come across exploring the nature of consiousness, reality, and immortality. (What, exactly does it mean for something to be 'REAL' anyway?) This is a futuristic work of fiction is set in a time when people can actually inhabit computers. A virtual reality simulation of consiousness might be more accurate. This book is spellbinding and thought-provoking. If they ever do invent such computers -- I want in! Don't worry about somebody telling you the ending -- you have to read the entire journey for it to have any meaning anyway. And what a journey it is! Throughout the book I was constantly wondering 'what in the world is going to happen next?' in very much the same sense as in WATERSHIP DOWN. The introduction is interesting and the pace picks up from there and never slows down. There is only one short scene which might jostle the squeamish and it doesn't impact the story line at all. As befits a book about immortality I was still hungry for more when I finished it but the book wraps up nicely and leaves one with a lot to ponder. I highly recommend this book.
