This is a special two-part podcast. First, Mark and Ariel discuss how AIs can use stories and creativity to understand and exhibit culture and ethics, while also gaining "common sense reasoning." They also discuss the “big red button” problem in AI safety research, the process of teaching "rationalization" to AIs, and computational creativity. Mark is an associate professor at the Georgia Tech School of interactive computing, where his recent work has focused on human-AI interaction and how humans and AI systems can understand each other.

Then, we hear from scientists, politicians and concerned citizens about why they support the upcoming UN negotiations to ban nuclear weapons. Ariel interviewed a broad range of people over the past two months, and highlights are compiled here, including comments by Congresswoman Barbara Lee, Nobel Laureate Martin Chalfie, and FLI president Max Tegmark.
