On the Our Opinions Are Correct podcast: Science Fiction Explains Our Messed Up Economy. Economist Noah Smith discusses how different theories of economics show up in science fiction, and how economics is itself an exercise in speculative worldbuilding. Also, the economic theory of “rational actors” pervades classic midcentury space opera, and everybody’s obsessed with game theory. And discussion of the most influential science fiction writer of the past century: Ayn Rand.
