David Louis Edelman asks a big question over at the author group-blog Deep Genre – when will science fiction end? In his own words: “I’m not asking this from a commercial standpoint so much as from an epistemological standpoint. Will there always be new science fiction? Or will the genre just wither up at some point and go away?” What do you think? Are we so immunised to the exponential curve of technological change that fiction based in extrapolated futures will cease to have any effect on us other than, perhaps, nostalgia?
