question for 2007 has been released: What are you optimistic about?
Read the 180 answers from a number of intellectuals across many different fields. There's responses from all kinds of people you may or may not have heard about: Brian Eno, Richard Dawkins, Ray Kurzweil, Larry Sanger, etc. It's good reading, and it goes on and on. Perhaps it will make you think!
