I arrived before he did, and waited in a hallway between two conference rooms. A plaque indicated that one of them was the Arkhipov Room, honoring Vasili Arkhipov, a Soviet naval officer. During the Cuban missile crisis, Arkhipov was serving on a submarine in the Caribbean when U.S. destroyers set off depth charges nearby. His captain, unable to establish radio contact with Moscow, feared that the conflict had escalated and ordered a nuclear strike. But Arkhipov dissuaded him, and all-out atomic war was averted. Across the hallway was the Petrov Room, named for another Soviet officer who prevented a global nuclear catastrophe. Bostrom later told me, “They may have saved more lives than most of the statesmen we celebrate on stamps.”

Although Bostrom did not know it, a growing number of people around the world shared his intuition that technology could cause
transformative change, and they were finding one another in an online discussion group administered by an organization in California called the Extropy Institute. The term “extropy,” coined in 1967, is generally used to describe life’s capacity to reverse the spread of entropy across space and time. Extropianism is a libertarian strain of transhumanism that seeks “to direct human evolution,” hoping to eliminate disease, suffering, even death; the means might be genetic modification, or as yet uninvented nanotechnology, or perhaps dispensing with the body entirely and uploading minds into
supercomputers. (As one member noted, “Immortality is mathematical, not mystical.”) The Extropians advocated the development of artificial superintelligence to achieve these goals, and they envisioned humanity colonizing the universe, converting inert matter into engines of civilization.

He believes that the future can be studied with the same
meticulousness as the past, even if the conclusions are far less firm. “It may be highly unpredictable where a traveller will be one hour after the start of her journey, yet predictable that after five hours she will be at her destination,” he once argued. “The verylong-term future of humanity may be relatively easy to predict.” He offers an example: if history were reset, the industrial revolution might occur at a different time, or in a different place, or perhaps not at all, with innovation instead occurring in increments over hundreds of years. In the short term, predicting technological achievements in the counter-history might not be possible; but after, say, a hundred thousand years it is easier to imagine that all the same inventions would have emerged.
Bostrom calls this the Technological Completion Conjecture: “If scientific- and technological-development efforts do not effectively cease, then all important basic capabilities that could be obtained through some possible technology will be obtained.” In light of this, he suspects that the farther into the future one looks the less likely it seems that life will continue as it is. He favors the far ends of possibility: humanity becomes transcendent or it perishes. …
Unexpectedly, by dismissing its founding goals, the field of A.I. created space for outsiders to imagine more freely what the technology might look like. Bostrom wrote his first paper on artificial superintelligence in the nineteen-nineties, envisioning it as potentially perilous but irresistible to both commerce and government. “If there is a way of guaranteeing that superior artificial intellects will never harm human beings, then such intellects will be created,” he argued. “If there is no way to have such a guarantee, then they will probably be created nevertheless.” His audience at the time was primarily other transhumanists. But the movement was maturing. In 2005, an organization called the Singularity Institute for Artificial Intelligence began to operate out of Silicon Valley; its primary founder, a former member of the Extropian discussion group, published a stream of literature on the dangers of A.I. That same year, the futurist and inventor Ray Kurzweil wrote “The Singularity Is Near,” a best-seller that prophesied a merging of man and machine in the foreseeable future. Bostrom created his institute at Oxford. …
The parable is his way of introducing the book’s core question: Will an A.I., if realized, use its vast capability in a way that is beyond human control? One way to think about the concern is to begin with the familiar. Bostrom writes, “Artificial intelligence already
outperforms human intelligence in many domains.” The examples range from chess to Scrabble. One program from 1981, called Eurisko, was designed to teach itself a naval role-playing game. After playing ten thousand matches, it arrived at a morally grotesque strategy: to field thousands of small, immobile ships, the vast majority of which were intended as cannon fodder. In a national tournament, Eurisko demolished its human opponents, who insisted that the game’s rules be changed. The following year, Eurisko won again—by forcing its damaged ships to sink themselves.

….worries that solving the “control problem”—insuring that a superintelligent machine does what humans want it to do—will require more time than solving A.I. does. The intelligence explosion is not the only way that a superintelligence might be created suddenly. Bostrom once sketched out a decades-long process, in which researchers arduously improved their systems to equal the intelligence of a mouse, then a chimp, then—after incredible labor—the village idiot. “The difference between village idiot and genius-level intelligence might be trivial from the point of view of how hard it is to replicate the same functionality in a machine,” he said. “The brain of the village idiot and the brain of a scientific genius are almost identical. So we might very well see relatively slow and incremental progress that doesn’t really raise any alarm bells until we are just one step away from something that is radically superintelligent.”

Stuart Russell, the co-author of the textbook “Artificial
Intelligence: A Modern Approach” and one of Bostrom’s most vocal supporters in A.I., told me that he had been studying the physics community during the advent of nuclear weapons. At the turn of the twentieth century, Ernest Rutherford discovered that heavy elements produced radiation by atomic decay, confirming that vast reservoirs of energy were stored in the atom. Rutherford believed that the energy could not be harnessed, and in 1933 he proclaimed, “Anyone who expects a source of power from the transformation of these atoms is talking moonshine.” The next day, a former student of Einstein’s named Leo Szilard read the comment in the papers. Irritated, he took a walk, and the idea of a nuclear chain reaction occurred to him. He visited Rutherford to discuss it, but Rutherford threw him out. Einstein, too, was skeptical about nuclear energy—splitting atoms at will, he said, was “like shooting birds in the dark in a country where there are only a few birds.” A decade later, Szilard’s insight was used to build the bomb.

Between the two conferences, the field had experienced a revolution, built on an approach called deep learning—a type of neural network that can discern complex patterns in huge quantities of data. For decades, researchers, hampered by the limits of their hardware, struggled to get the technique to work well. But, beginning in 2010, the increasing availability of Big Data and cheap, powerful
video-game processors had a dramatic effect on performance. Without any profound theoretical breakthrough, deep learning suddenly offered breathtaking advances. “I have been talking to quite a few
contemporaries,” Stuart Russell told me. “Pretty much everyone sees examples of progress they just didn’t expect.” He cited a YouTube clip of a four-legged robot: one of its designers tries to kick it over, but it quickly regains its balance, scrambling with uncanny
naturalness. “A problem that had been viewed as very difficult, where progress was slow and incremental, was all of a sudden done. Locomotion: done.”

In recent years, Google has purchased seven robotics companies and several firms specializing in machine intelligence; it may now employ the world’s largest contingent of Ph.D.s in deep learning. Perhaps the most interesting acquisition is a British company called DeepMind, started in 2011 to build a general artificial intelligence. Its founders had made an early bet on deep learning, and sought to combine it with other A.I. mechanisms in a cohesive architecture. In 2013, they published the results of a test in which their system played seven classic Atari games, with no instruction other than to improve its score. For many people in A.I., the importance of the results was immediately evident. I.B.M.’s chess program had defeated Garry Kasparov, but it could not beat a three-year-old at tic-tac-toe. In six games, DeepMind’s system outperformed all previous algorithms; in three it was superhuman. In a boxing game, it learned to pin down its opponent and subdue him with a barrage of punches.
Weeks after the results were released, Google bought the company, reportedly for half a billion dollars. DeepMind placed two unusual conditions on the deal: its work could never be used for espionage or defense purposes, and an ethics board would oversee the research as it drew closer to achieving A.I. Anders Sandberg had told me, “We are happy that they are among the most likely to do it. They recognize there are some problems.”

“I could give you the usual arguments,” Hinton said. “But the truth is that the prospect of discovery is too sweet.” He smiled awkwardly, the word hanging in the air—an echo of Oppenheimer, who famously said of the bomb, “When you see something that is technically sweet, you go ahead and do it, and you argue about what to do about it only after you have had your technical success.”
