risk easily managed and far in the future, but also it’s extremely unlikely that we'd even try to move billions of humans to Mars in the first place. The analogy is a false one, however. We are already devoting huge scientific and technical resources to creating ever-more-capable AI systems. A more apt analogy would be a plan to move the human race to Mars with no consideration for what we might breathe, drink, or eat once we'd arrived. e Human-level AI isn’t really imminent, in any case. The AI100 report, for example, assures us, “Contrary to the more fantastic predictions for AI in the popular press, the Study Panel found no cause for concern that AI is an imminent threat to humankind.” This argument simply misstates the reasons for concern, which are not predicated on imminence. In his 2014 book, Superintelligence: Paths, Dangers, Strategies, Nick Bostrom, for one, writes, “It is no part of the argument in this book that we are on the threshold of a big breakthrough in artificial intelligence, or that we can predict with any precision when such a development might occur.” e You're just a Luddite. It’s an odd definition of Luddite that includes Turing, Wiener, Minsky, Musk, and Gates, who rank among the most prominent contributors to technological progress in the 20th and 21st centuries.* Furthermore, the epithet represents a complete misunderstanding of the nature of the concerns raised and the purpose for raising them. It is as if one were to accuse nuclear engineers of Luddism if they pointed out the need for control of the fission reaction. Some objectors also use the term “anti-AI,” which is rather like calling nuclear engineers “anti-physics.” The purpose of understanding and preventing the risks of AI is to ensure that we can realize the benefits. Bostrom, for example, writes that success in controlling AI will result in “a civilizational trajectory that leads to a compassionate and jubilant use of humanity’s cosmic endowment”—hardly a pessimistic predict
