I'm with iguana on this. I reckon if the name changed to science fantasy, it would do away with two of the major problems of the science fiction genre; 1) that it's too unattractively geeky to be cool and 2) that the 'science' is bunk. So then you would have fantasy and science fantasy, which a very small niche for the totally geeky true science fiction.
Back in the 1970's, writers in Starlog
referred to Star Wars
as science fantasy,
since it was regarded as in between science fiction and fantasy, as it were.
