But what (in hell!) do Game of Thrones and books of that ilk have in common with science-based fiction?  I'm interested in speculations about where technology is leading us, the nature of intelligence and its place in the universe.  It doesn't follow that I should be interested in dragons and medieval-ish knights and battling elves.

... me, I wouldn't call fantasy, sword + sorcery, whatever,
"speculative" (though The Sword of Shannara et al. have
postapocalyptic SF trappings).  "Speculating" on what?  What if the
supernatural was natural?
