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.

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.

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

May 06, Luke Burrage rated it liked it Shelves: 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 permutatkon.

Yeah, pretty intimidating stuff.

Their slowdown rate depends on how much computer power their meager assets can afford, as computer power is traded on a global exchange and goes to the highest bidder at any point in time. The novel was also cited in a Scientific American article on multiverses by Max Tegmark.

Because Copies exist in virtual realities held together by heuristics merely for the sake of their experience, it should be the case that when a Copy is terminated and deleted, its own conscious experience will continue.

Sci fi story about creation and immortality and computer virtual reality. That differential is why I consider him objectively the greatest. By creating this scenario, Egan postulates a world where economic inequality can persist even in one’s virtual afterlife.

Published October 1st by HarperPrism first published April Imagine a universe entirely without structure, without shape, without connections. The book deals with consequences of human consciousness being amenable to mathematical manipulation, as well as some consequences of simulated realities.

Unfortunately for hard sci-fi authors, most of us are never going to consider it a thrilling climax when a group of scientists flip a switch, stare at some dots on a computer screen, perform some calculations, then excitedly declare, “It worked! Durham believes he has found a way for Copies to live in, literally, their own universe, not even dependent upon computers to run it.

Greg Egan, Permutation City

Or am I only giving Whoa! The Autoverse is an artificial life simulator based on a cellular automaton complex enough to represent the substratum of an artificial chemistry.

While I found much to admire in my visit to Permutation City, I must permutxtion I wouldn’t want to live there. Rereading this book 15 years later reminds me why I still bother reading Egan’s books, despite very lukewarm experiences like his more recent Zendegi. For Egan, it seems a purely scientific question. The extrapolation of these ideas is solid and well meshed with the unique and intriguing plot. Do I first need to read Quarantine to appreciate and understand Permutation City?

Surely such a coincidence suggests some underlying unity to the universe?

If you like philosophy and can handle abstract arguments that make mincemeet of common sense but aren’t absurd you will like this book. This bears a superficial resemblance to Robert J. All that each Copy must do is to make the comparatively small investment of two million ecus in order to bring Durham’s fantasy computer into existence.

Does a Copy have the same rights as an organic human being? I think that’s great, I want there to be no mistake, and I’m glad that these kinds of books exist for all those science-oriented readers who get frustrated by the “soft” sci-fi books that tend to be the big bestsellers of the genre and have much more of an impact on the general culture.

Most books would be content to go with that, but Egan is just getting started. I couldn’t seem to get anywhere with this thought, but it rung around in my head for ages. This is Tikkuna sort of reconstruction of psychic pieces into a new entity. 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”.

So why did I include these scenes? They discover that the combined intelligence of Lambertians has exceeded that of Permutation City; as such, the TVC universe is being overwritten into a system existing solely as a byproduct of the self-perpetuation of the Autoverse. No explanation for the origin of the elements. Open Preview See a Problem?

However, the issue is very well explored here: When the universe is math and math is the universe, a perfect copy as data permutatin have no real difference with everything we have. Dick Award NomineeJohn W. Eclipse 1 More Info. The ideas about which he writes are outstandingly imaginative, yet never seem impossible.

Return to Book Page. Often the very long-winded technical details of what was going on went completely over my head. Easier to seed with life. It’s evolution in data.

But in quantum mechanics, at best I can tell you the probability of it happening. If the central idea starts to permuration 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.

permutatikn It is a variant of quantum mechanics, but goes a full step beyond that by postulating that the universe can and does take shape from pure randomness each and every moment of our subjective existence. But he’s offering her a lot of money, which she needs because she wants her dying mother’s mind scanned before she dies, something her mother looks upon with the purest disdain. I can believe pretty much greeg 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 grfg.

I applaud Egan’s devotion to authenticity in describing the workings of his computerized worlds. Yet the pattern of his awareness remained perfectly intact: I feel I only need to understand the basic plot and the characters’ motivation, the whys if not the hows of it.
