What determines our visions of the future, and how those visions change over time? How is politics shaped by conflicting visions of the future? What did the old mid-century vision of a Jetsons-style future get wrong -- and what did it get right that we are now struggling to rediscover? What are the roots of technological pessimism, and how can we encourage the growth of a culture that valorizes scientific and technological advance? On this episode of The Permanent Problem podcast, author Virginia Postrel (The Future and Its Enemies, The Fabric of Civilization, and more) joins the Niskanen Center's Brink Lindsey to discuss the ongoing and ever-changing struggle between the forces and champions of dynamism and progress and those that favor the status quo or an imagined past.
