A.I. Will Fix the World. The Catch? Robots in Your Veins.

THE SINGULARITY IS NEARER: When We Merge With A.I., by Ray Kurzweil

A central conviction held by artificial intelligence boosters, but largely ignored in public discussions of the technology, is that the ultimate fulfillment of the A.I. revolution will require the deployment of microscopic robots into our veins.

In the short term, A.I. may help us print clothing on demand, help prevent cancer and liberate half of the work force. But to achieve its greatest aims — immortality, superhuman intelligence, the elimination of all our social ills — we must infuse our blood with millions of self-replicating diamondoid robots.

Why don’t we hear more about the blood robots? Their arrival is only a few years away — at least according to Ray Kurzweil, a godfather of A.I., our foremost technological prophet and a “principal researcher and A.I. visionary” at Google.

“The Singularity Is Nearer” follows Kurzweil’s 2005 “The Singularity Is Near,” and several other heraldic works of tech futurism that have become sacred texts to the current generation of A.I. utopians. In his latest, Kurzweil boasts of his greatest hits: his prediction, in the late 1980s, that a global information network would be universally accessible by the late 1990s, and that mobile devices linked to this network would appear by the turn of the century; his 2018 prediction that, within two years, a neural net would be able to analyze radiology images as well as human doctors, a feat accomplished by Stanford researchers two weeks later; and his 1999 prediction that an A.I. capable of convincingly impersonating a human being would appear by 2029 — which now may seem conservative.

In “The Singularity Is Nearer,” Kurzweil promises that, by 2029, A.I. will be “better than all humans” in “every skill possessed by any human.” During the 2030s, solar power, enhanced by A.I.-driven advances in 3-D printing, will come to dominate the global energy supply, most consumer goods will be free, and the “dramatic reduction of physical scarcity” will “finally allow us to easily provide for the needs of everyone.” Sounds rad!
