Dune Has a Desert Problem

Good science fiction (in my opinion) isn't just about technological advancements in a future world that just happens to be socio-politically identical to our own. In fact, the most dated and ignored science fiction of the 1950s has just this problem - a stultified 1950's society transplanted to outer space, somehow unchanged over the centuries.
In science fiction, you get to play with not just future technologies, but also future societies, future religions, future races and cultures, future ecosystems and so on. The author of this piece doesn't seem to grasp that concept, or that the reason for the persistence of the Frank Herbert Dune books is that they aren't fixed in the social era in which they were written.
