Episode 28: What is the future of the human race? Does it even have one? Alex and Muna discuss the threats of nuclear war (past and present), climate change, AIDS, the power of fear and how it's used by media and politicians to give us a sense of impending doom, the almost-inevitable (to Alex) AI takeover, viruses in brain chips, overpopulation, declining sperm counts and a new perspective on Darwin's theory of evolution. Muna counters the gloom with some positive stories from around the world and a large dollop of empathy.
