An attractive picture of a plausible future; in 20 years, we may know if it actually works.
Worried about the Singularity? Fear not—here's the lowdown from an expert.
The Singularity, almost an article of faith in techie circles, is the point at which machine intelligence outstrips human brainpower. Kurzweil (The Age of Spiritual Machines, 1999, etc.) spends much time stressing the point that progress in the computer field moves at exponential rates. By his reckoning, the raw power of information technologies is doubling annually. This power increase, combined with the predicted growth of nanotechnology—robots the size of red blood cells inserted into the body—will make possible, within two decades, complete scanning of the human brain. By then, computer hardware should be capable of running accurate software models of human intelligence. By the end of the 2020s, computers will pass the Turing Test, simulating a living person well enough to fool an interrogator. At that point, Kurzweil believes, a genuine synthesis of the strengths of human and machine intelligence becomes possible: pattern recognition and inference on the human side, large memory with instant recall and easy data-sharing on the machine side. Freed from the built-in limitations of the brain, machine intelligence will then be able to use nanotechnological design to far exceed human intelligence. But at the same time, nanotechnological implants can be used to augment human brains, creating a hybrid intelligence unlike anything previously known. Ultimately, Kurzweil predicts, the predominant component of human intelligence will be non-biological, and more of our experiences will take place in virtual reality than in the physical world. Human-machine intelligence will saturate the immediate vicinity of the Earth, and eventually grow to fill the universe. Kurzweil backs his predictions with numerous citations of other experts, and while some of the arguments are dense, the book repays close attention.

An intriguing meditation on the nature of the universe and our attempts to understand it that should appeal to both...
Italian theoretical physicist Rovelli (General Relativity: The Most Beautiful of Theories, 2015, etc.) shares his thoughts on the broader scientific and philosophical implications of the great revolution that has taken place over the past century.
These seven lessons, which first appeared as articles in the Sunday supplement of the Italian newspaper Sole 24 Ore, are addressed to readers with little knowledge of physics. In less than 100 pages, the author, who teaches physics in both France and the United States, cogently covers the great accomplishments of the past and the open questions still baffling physicists today. In the first lesson, he focuses on Einstein's theory of general relativity. He describes Einstein's recognition that gravity "is not diffused through space [but] is that space itself" as "a stroke of pure genius." In the second lesson, Rovelli deals with the puzzling features of quantum physics that challenge our picture of reality. In the remaining sections, the author introduces the constant fluctuations of atoms, the granular nature of space, and more. "It is hardly surprising that there are more things in heaven and earth, dear reader, than have been dreamed of in our philosophy—or in our physics,” he writes. Rovelli also discusses the issues raised in loop quantum gravity, a theory that he co-developed. These issues lead to his extraordinary claim that the passage of time is not fundamental but rather derived from the granular nature of space. The author suggests that there have been two separate pathways throughout human history: mythology and the accumulation of knowledge through observation. He believes that scientists today share the same curiosity about nature exhibited by early man.

Loads of good explaining, with reminders, time and again, of how much remains unknown, neatly putting the death of science...
Bryson (I'm a Stranger Here Myself, 1999, etc.), a man who knows how to track down an explanation and make it confess, asks the hard questions of science—e.g., how did things get to be the way they are?—and, when possible, provides answers.
As he once went about making English intelligible, Bryson now attempts the same with the great moments of science, both the ideas themselves and their genesis, to resounding success. Piqued by his own ignorance on these matters, he’s egged on even more so by the people who’ve figured out—or think they’ve figured out—such things as what is in the center of the Earth. So he goes exploring, in the library and in company with scientists at work today, to get a grip on a range of topics from subatomic particles to cosmology. The aim is to deliver reports on these subjects in terms anyone can understand, and for the most part, it works. The most difficult is the nonintuitive material—time as part of space, say, or proteins inventing themselves spontaneously, without direction—and the quantum leaps unusual minds have made: as J.B.S. Haldane once put it, “The universe is not only queerer than we suppose; it is queerer than we can suppose.” Mostly, though, Bryson renders clear the evolution of continental drift, atomic structure, singularity, the extinction of the dinosaur, and a mighty host of other subjects in self-contained chapters that can be taken at a bite, rather than read wholesale. He delivers the human-interest angle on the scientists, and he keeps the reader laughing and willing to forge ahead, even over their heads: the human body, for instance, harboring enough energy “to explode with the force of thirty very large hydrogen bombs, assuming you knew how to liberate it and really wished to make a point.”
Loads of good explaining, with reminders, time and again, of how much remains unknown, neatly putting the death of science into perspective.Pub Date: May 6, 2003
