On the site Edge.org  discussed the dangers of artificial intelligence (AI) in November, led by Stephen Hawking and philosopher Nick Bostrom has recently warned of what superior and possibly malevolent artificial intelligences could get up to. Only two people were worth reading: Jaron Lanier  , which is critical to AI, and Rodney Brooks  , which is positive. ...
From the self to left brain vs. right brain to romantic love, a catalog of broken theories that hold us back from the conquest of Truth.
“To kill an error is as good a service as, and sometimes even better than, the establishing of a new truth or fact,” asserted Charles Darwin in one of the eleven rules for critical thinking known as Prospero’s Precepts. If science and human knowledge progress in leaps and bounds of ignorance, then the recognition of error and the transcendence of falsehood are the springboard for the leaps of progress. That’s the premise behind This Idea Must Die: Scientific Theories That Are Blocking Progress  (public library ) — a compendium of answers Edge  founder John Brockman collected by posing his annual question  — “What scientific idea is ready for retirement?” — to 175 of the world’s greatest scientists, philosophers, and writers. Among them are Nobel laureates, MacArthur geniuses, and celebrated minds like theoretical physicist and mathematician Freeman Dyson, biological anthropologist Helen Fisher, cognitive scientist and linguist Steven Pinker, media theorist Douglas Rushkoff, philosopher Rebecca Newberger Goldstein, psychologist Howard Gardner, social scientist and technology scholar Sherry Turkle, actor and author Alan Alda, futurist and Wired founding editor Kevin Kelly, and novelist, essayist, and screenwriter Ian McEwan.
Brockman paints the backdrop for the inquiry:
Science advances by discovering new things and developing new ideas. Few truly new ideas are developed without abandoning old ones first. As theoretical physicist Max Planck (1858–1947) noted, “A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.” In other words, science advances by a series of funerals.
Many of the answers are redundant — but this is a glorious feature rather than a bug of Brockman’s series, for its chief reward is precisely this cumulative effect of discerning the zeitgeist of ideas with which some of our era’s greatest minds are tussling in synchronicity. They point to such retirement-ready ideas as IQ, the self, race, the left brain vs. right brain divide, human nature and essentialism, free will, and even science itself. What emerges is the very thing Carl Sagan deemed vital to truth in his Baloney Detection Kit — a “substantive debate on the evidence by knowledgeable proponents of all points of view.” ...
Complement This Idea Must Die , the entirety of which weaves a mind-stretching mesh of complementary and contradictory perspectives on our relationship with knowledge, with some stimulating answers to previous editions of Brockman’s annual question, exploring the only thing worth worrying about  (2013), the single most elegant theory of how the world works  (2012), and the best way to make ourselves smarter  (2011).
