What should we be worried about? Real Scenarios that keep scientists up at night. This is the title of the new book edited by the literary agent John Brockman, founder of the website Edge.org, a discussion forum that includes novelist Ian McEwan, musician Brian Eno, physicists Frank Wilczek and Freeman Dyson, as well as yours truly, 13.7's Tania Lombrozo, and a couple of hundred of other academics and intellectuals. Every year, Brockman asks this group a "question." Answers in the form of short essays are compiled in paperback volumes with the intention of providing food for thought, as well as showcasing some of the cutting-edge ideas in science and technology and how they shape our culture. This is year, nothing less than 150 answers were published, of which I provide a meager sample here.
