Bret Victor was once a "Human Interface Inventor" for Apple, and was apparently key to the iOS/tablet efforts at the company. In this hour-long presentation to CUSEC (Canadian University Software Engineering Conference), he delivers a stirring manifesto for interaction design and relates it to having a principled stand on technology and ethics. It's an extraordinary presentation, first for the dazzling technology on display, and second for the thoughtful way Victor connects it to a larger question of human ethics and life.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
