I recently read a collection of novels by a prominent 1960s science fiction writer. In three novels and 400 pages, I don’t think there was a single female character who advanced the plot other than by sexually entertaining a male character (Despite one of the books having a female title character, and another had a lot of minor female characters.) I know it’s a product of its era, but even then, there were more woman PhDs than men who’d been to space, so I think a good science fiction author ought to be able to at least imagine the possibility. I have nothing against female sexuality, but the most interesting women supplement it with some other talent.
