In the StarTalk podcast episode "The End of The World," Neil deGrasse Tyson interviews Josh Clark, co-host of "Stuff You Should Know" and creator of "The End of the World with Josh Clark," about existential risks to humanity. They discuss the popularity of learning and the potential dangers of artificial intelligence (AI), with Josh suggesting that AI is the biggest threat due to the lack of understanding of how to create friendliness in AI. They also touch on the possibility of AI becoming super intelligent and the difficulty of containing it. The hosts also discuss the skills needed in a post-apocalyptic world and the concept of the "great filter" that prevents life from expanding beyond its planet. They answer listener questions about extraterrestrial life and biased news. In another episode, Chuck Nice interviews Josh Clark about existential risks, the technological singularity, and the possibility of our universe being someone else's Large Hadron Collider. Clark shares his hope for a more peaceful world and provides advice on staying informed about current developments in the study of existential risks.
