The great inventor and futurist Ray Kurzweil is one of the best-known and controversial advocates for the role of machines in the future of humanity. In his latest, thrilling foray into the future, he envisions an eventthe "singularity"in which technological change becomes so rapid and so profound that our bodies and brains will merge with our machines.

The Singularity Is Near portrays what life will be like after this eventa human-machine civilization where our experiences shift from real reality to virtual reality and where our intelligence becomes nonbiological and trillions of times more powerful than unaided human intelligence. In practical terms, this means that human aging and pollution will be reversed, world hunger will be solved, and our bodies and environment transformed by nanotechnology to overcome the limitations of biology, including death.

We will be able to create virtually any physical product just from information, resulting in radical wealth creation. In addition to outlining these fantastic changes, Kurzweil also considers their social and philosophical ramifications. With its radical but optimistic view of the course of human development, The Singularity Is Near is certain to be one of the most widely discussed and provocative books of 2005.

"Renowned inventor Kurzweil (The Age of Spiritual Machines) may be technology's most credibly hyperbolic optimist. Elsewhere he has argued that eliminating fat intake can prevent cancer; here, his quarry is the future of consciousness and intelligence. Humankind, it runs, is at the threshold of an epoch ('the singularity,' a reference to the theoretical limitlessness of exponential expansion) that will see the merging of our biology with the staggering achievements of 'GNR' (genetics, nanotechnology and robotics) to create a species of unrecognizably high intelligence, durability, comprehension, memory and so on. The word 'unrecognizable' is not chosen lightly: wherever this is heading, it won't look like us. Kurzweil's argument is necessarily twofold: it's not enough to argue that there are virtually no constraints on our capacity; he must also convince readers that such developments are desirable. In essence, he conflates the wholesale transformation of the species with 'immortality,' for which read a repeal of human limit. In less capable hands, this phantasmagoria of speculative extrapolation, which incorporates a bewildering variety of charts, quotations, playful Socratic dialogues and sidebars, would be easier to dismiss. But Kurzweil is a true scientist — a large-minded one at that — and gives due space both to 'the panoply of existential risks' as he sees them and the many presumed lines of attack others might bring to bear. What's arresting isn't the degree to which Kurzweil's heady and bracing vision fails to convince — given the scope of his projections, that's inevitable — but the degree to which it seems downright plausible.
