chrisd writes "The Edge 2008 question (with answers) is in. This year, the question is: 'What did you change your mind about and why?'. Answers are featured from scientists as diverse as Richard Dawkins, Simon Baron-Cohen, George Church, David Brin, J. Craig Venter and the Astronomer Royal, Lord Martin Rees, among others. Very interesting to read. For instance, Stewart Brand writes that he now realizes that 'Good old stuff sucks' and Sam Harris has decided that 'Mother Nature is Not Our Friend.' What did Slashdot readers change their minds about in 2007?"
