Rather meta--today's Futurist Friday is about why you should read (good) science fiction for a glimpse of realistic futures. This 8 minute video from PBS Digital Studios includes clips and quotes from many of the greats, notably Isaac Asimov, Arthur C. Clarke, Philip K. Dick and (all time fav!) H. G. Wells.
The often spookily accurate visions these authors painted in the past of their future (& our present) should encourage you to look for the equivalent current visions of the future to come. Includes tips on how to spot good science fiction--look for writing that is grounded in good science. Enjoy!
