SF runs the gamut. I enjoy the hardest of the hard science fiction a'la the Martian but I like a good space opera, too. Like the author said at the beginning of the article, a lot of SF is about character (first) and metaphor. If an author has to invent a method for unspooling pocket dimensions do dump heat into for the sake of the story, so be it.
