In this episode of the Waking Up podcast, Sam Harris talks to physicist David Deutsch about the reach and power of human knowledge, the future of artificial intelligence, and the survival of civilization.
David Deutsch is best known as the founding father of the quantum theory of computation, and for his work on Everettian (multiverse) quantum theory. He is a Visiting Professor of Physics at Oxford University, where he works on “anything fundamental.” At present, that mainly means his proposed constructor theory. He has written two books – The Fabric of Reality and The Beginning of Infinity – aimed at the general reader.
Wherein Sam and Joe talk for 4.5 hours…
Known as “Mad Max” for his unorthodox ideas and passion for adventure, Max Tegmark’s scientific interests range from precision cosmology to the ultimate nature of reality, all explored in his new popular book Our Mathematical Universe. Tegmark is a professor of physics who has published more than two hundred technical papers and been featured in dozens of science documentaries. His work with the Sloan Digital Sky Survey on galaxy clustering shared the first prize in Science magazine’s “Breakthrough of the Year: 2003.” For more information about his work, please visit his MIT website and the Future of Life Institute.
For decades, Noam Chomsky has been one of the most prominent critics of U.S. foreign policy, and the further left one travels along the political spectrum, the more one feels his influence. Although I agree with much of what Chomsky has said about the misuses of state power, I have long maintained that his political views, where the threat of global jihadism is concerned, produce dangerous delusions. In response, I have been much criticized by those who believe that I haven’t given the great man his due.
Last week, I did my best to engineer a public conversation with Chomsky about the ethics of war, terrorism, state surveillance, and related topics. As readers of the following email exchange will discover, I failed. I’ve decided to publish this private correspondence, with Chomsky’s permission, as a cautionary tale. Clearly, he and I have drawn different lessons from what was, unfortunately, an unpleasant and fruitless encounter. I will let readers draw lessons of their own.
Sam Harris gets back in the VBW ring for another round on moral responsibility, ethical theories, and the grounds for our obligations to other people. Are we at a genuine stalemate when it comes to blame and desert? Is Tamler a closet consequentialist? Is Sam a closet pluralist? Why is Dave such a big Wagner fan? Plus, Twitter shaming: what is it good for? Settle in, get comfortable, pour yourself a drink, you’re in for the long haul on this one.
Michael Shermer is the Publisher of Skeptic magazine, a monthly columnist for Scientific American, the host of the Skeptics Distinguished Science Lecture Series at Caltech, and a Presidential Fellow at Chapman University. His latest book is The Moral Arc: How Science and Reason Lead Humanity Toward Truth, Justice, and Freedom.
Michael was kind enough to answer a few questions by email:
It seems increasingly likely that we will one day build machines that possess superhuman intelligence. We need only continue to produce better computers—which we will, unless we destroy ourselves or meet our end some other way. We already know that it is possible for mere matter to acquire “general intelligence”—the ability to learn new concepts and employ them in unfamiliar contexts—because the 1,200 cc of salty porridge inside our heads has managed it. There is no reason to believe that a suitably advanced digital computer couldn’t do the same.
It is often said that the near-term goal is to build a machine that possesses “human level” intelligence. But unless we specifically emulate a human brain—with all its limitations—this is a false goal. The computer on which I am writing these words already possesses superhuman powers of memory and calculation. It also has potential access to most of the world’s information. Unless we take extraordinary steps to hobble it, any future artificial general intelligence (AGI) will exceed human performance on every task for which it is considered a source of “intelligence” in the first place. Whether such a machine would necessarily be conscious is an open question. But conscious or not, an AGI might very well develop goals incompatible with our own. Just how sudden and lethal this parting of the ways might be is now the subject of much colorful speculation.
