i'm going to have to side with Zilla on this one, just because something is set in the future doesn't make it our reality,
a prime example is jurrasic park, since it was set in the present day that made it alternate reality fiction according to you Puks, but if it was set 10 years in the future that makes it science fiction in our reality? what happens when future events in the timeline in a book or movie begins to happen in the past.
at what point did 2001: A Space Odyssey, or Forever War, or Soylent Green, stop being our reality and became another?
