"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?"
