Each year the website Edge.org, considered by many one of the publications of higher intellectual quality in the world, brings together hundreds of artists, scientists and the most renowned thinkers in the world and asks them a question, creating a kind of itinerant think thank that seeks dialogue and anticipates major issues facing humanity, or sometimes simply celebrates knowledge. This year the question was: "What Should We Be Worried About?", under the argument that "we are concerned because we are able to anticipate the future. Nothing can be done that we no longer worry about, but science can teach us how better care, and when stop worrying."
Some of the answers compiled by Edge.org, are remarkable essays on the most pressing problems of the modern civilization modern; others are simply ironic (of course, predominantly about rational thought and science oriented). Worth taking a tour of this panorma today.
