Damn fine science fiction 23 May 2014
By Blake Senftner - Published on Amazon.com
Format: Kindle Edition
If you like honest treatment of complex issues, like the nature of consciousness, freedom in a technological society, security in today's global environments, and interpersonal relationships between the stressed out individuals living in this too-close-for-comfort world. You will like Dualism. The pacing is even and steady, with a continual flow of thought provoking ideas that kept my self conversation going for days. This is Hard Science Fiction at it's best: believable and seemingly not far away.

The best of AI and physics science fiction 23 May 2014
By Olivia Pauli - Published on Amazon.com
Format: Kindle Edition
In his second novel, DeSmedt, artificial intelligence researcher as well as novelist, explores what might happen if quantum entanglement could be harnessed to create an analytical hive-mind that uses instantaneous thought transmission across a horde of experts to solve the world's knottiest problems. Meanwhile, a neural net AI running on a quantum computer spars with the hero Jonathan Knox over fundamental questions of existence -- both the AI's and Knox's.

In the best hard SF tradition, DeSmedt takes us to a place that we've never imagined but that is scarily plausible. What will be especially appealing to hard SF fans is the way DeSmedt weaves into the narrative real scientific objections to the technology in question, and then demonstrates credible ways to get around those objections. He did the same thing in his first novel, Singularity, which addressed up-to-the-moment questions in high-energy physics (black holes, time travel), and has been blessed as scientifically accurate by top physicists from CalTech and MIT (if you're interested, see DeSmedt's personal website, billdesmedt dot com).

Read them both. They're mind-candy for science groupies (you know who you are).

If you like superspy adventure stories but wish they had more hard ... 5 Aug 2014
By Karel P. Kerezman - Published on Amazon.com
Format: Hardcover
What Bill DeSmedt did for black holes in Singularity he's done for artificial intelligence (and nanotechnology and brain surgery and...) in Dualism. If you like superspy adventure stories but wish they had more hard SF woven in, this is where you want to be. You'll laugh, you'll cry, you'll scratch your head in wonderment.

Note that this is an adventure first, a hard-SF treatment second. You have to take a grain of salt, let the author run with the extrapolation of current theories and technologies, and enjoy the ride. If you're the kind of person whose intelligence will be insulted by anything less than absolute adherence to today's state of the art and strict scientific limitations, you probably aren't much fun at parties either. That said, there's still a lot of good food for thought in here, both about where technology might take us and what it all means, in the end. And it's all based on sound research and the latest theories.

Oh, and there's butt-kicking plus explosions plus gizmos. I didn't mention that? My bad.

At any rate: While I think I like Singularity more, Dualism is absolutely a worthy follow-up. Bring on the third volume!

An impressive achievment: a second book better than the first. 8 July 2014
By Richard C. Waters - Published on Amazon.com
Format: Kindle Edition Verified Purchase
I bought Dualism because I had read singularity and liked it. In short, I liked Dualism even more. I think it is a bit more well rounded and bit betterl written. Having a first book that is good is very hard. Following it up with a second book that is better is a great deal harder!

As a computer scientist I appreciate that all the statements about current AI technology are accurate and the projections about near future technology are very plausible. As for projections of farther future technology, only time will tell about plausibility but there is no doubt that the ideas are novel and interesting.

I also liked the fact that except for centering on the same two characters, it is not a sequel to Singularity at all, but a completely different story involviing completely different science.

Its a page turner from beginning to end.

Sophisticated story about a high tech plot to destroy the USA (Great Satan) 6 Dec 2014
By TomQ - Published on Amazon.com
Format: Kindle Edition Verified Purchase
Excellent story. Muslim terrorists (so probably not a candidate for a movie, Hollywood would see this plot as non Politically Correct no doubt). Artificial Intelligence, A frightening plot to destroy the USA (Great Satan). Several of the main characters in the book "Singularity" reprise their roles in this book, so probably a good idea to read that book first, although not mandatory. Lots of hard science / science fiction / science speculation thrown into the mix. An enjoyable read.
