That’s what Hanna Pickard argues. After analyzing the scientific research, and working with those who’ve stopped self-destructive drug and alcohol use, the Johns Hopkins philosopher sees addiction as a complex behavioural disorder. She argues it’s driven by individual psychology and social circumstances, and should be treated that way. Jowita Bydlowska and Michael Kaufmann, both memoirists of addiction, weigh in. *This episode originally aired on March 3, 2026.

Hidden in the 1950 academic paper that launched the famous 'Turing Test' of machine intelligence, is a strange mystery. Cryptographer Alan Turing argued that humans might always be able to outsmart machines, because we have supernatural powers like ESP, telepathy, and telekinesis. His belief in the paranormal is just one part of the spooky side of artificial intelligence. Like hauntings or seances, AI is an exercise in self-deception; we imagine intelligence from computation and data, just like we imagine ghosts from strange lights and bumps in the night. *This episode originally aired on March 12, 2025.
