Jamie and his AI companion Jimmy Botlett become increasingly difficult to tell apart as they bring you the final chapter of this story - featuring Geoffrey Hinton, the godfather of AI, who now wishes he'd thought harder about the consequences.

But what's true, what's fake, and what does any of it say about what's happening to all of us, right now?
