Permutation City

Gavin

The best-written info-dump ever. Egan's predictions for the near-future are looking really good 25 years on: the dominance of cloud computing, the digital-nomad life, spam filters, molecular-chem composer VR ... Still some amusing bits of course, e.g. "He was using more computing power than Fujitsu."

 Reading about the legal expert-system she has free access to, I itched for the future to arrive.

There are a few logical holes in the plot which Egan helpfully erratas here.

The story of a man with a vision - immortality : for those who can afford it is found in cyberspace. Permutation city is the tale of a man with a vision - how to create immortality - and how that vision becomes something way beyond his control. Encompassing the lives and struggles of an artificial life junkie desperate to save her dying mother, a billionaire banker scarred by a terrible crime, the lovers for whom, in their timeless virtual world, love is not enough - and much more - Permutation city is filled with the sense of wonder.

Bouke van der Bijl

OK book with some cool ideas that's hampered by poor writing.

I'd also like to instate a rule: if you write hard sci-fi, just don't write a sex scene. Just don't

Gary Homewood

Completely believable hard sci fi about simulated universes, software copies of humans, evolutionary intelligence and quantum ontology.
