Apple unveiled its latest gadgets at its big September event on Monday. We discuss the most interesting new features — including AirPods that can function as hearing aids and Apple Watch software that can help detect sleep apnea — and offer our advice on when to buy a new iPhone. Then, the best-selling author Yuval Noah Harari joins us to discuss his new book and his biggest fears about A.I. And finally, we crack open some criminal cases in a new segment we’re calling the Hard Fork Crimes Division. We’ll explain how one man made $10 million by manipulating music streaming services and how online instructions for building a 3D-printed gun have ended up in the hands of criminals around the world.

Guest:

  • Yuval Noah Harari, author of “Sapiens,” “Homo Deus” and “Nexus.”
