Seems to me that there's huge fluctuations in what sci-fi actually
IS and what some readers/authors
NEED/WANT it to be. Perception is reality. All the contention (and definition) is basically pointless. I let the authors classify their own work. If they choose not to... then
my opinion is the only one I'll recognize on the subject.
As to the idea that science-fiction is lying in a ditch, bleeding from the mouth and rectum, and generally looking terminal..... hogwash.
