Rory Cellan-Jones talks to the artist who has created a "deepfake" Mark Zuckerberg to put Facebook on the spot over privacy. Also in the programme, Rory gets behind the hype over artificial intelligence and talks with the head of Moonshots at Google X, Astro Teller, about whether AI is finally becoming mainstream. And in a busy week for London's tech scene, Rory visits the Founders Forum to hear from the Europeans who want to impose tighter controls on the giant American technology companies. Special guest throughout the programme is Tabitha Goldstaub who runs the CogX festival of Artificial Intelligence.
