At the end of this week Newsnight as we know it comes to an end. From Tuesday, its format will change – and it’ll be shorter too. To discuss the end of an era, Katie and Ros speak to an all-star Newsnight line up: Kirsty Wark, Peter Snow, Michael Crick. They're also joined by Professor Suzanne Franks, who researches changing broadcast news consumption. On Saturday, Oleksandr Usyk beat Tyson Fury to become boxing's undisputed heavyweight champion. The high-profile match was held in the Kingdom Arena in Riyadh, Saudi Arabia, which has been accused of ‘sportswashing’. Alex Pattle from The Independent reveals what it was like reporting from the event, and Prof Simon Chadwick analyses the Saudi sports investment strategy. The actor Scarlett Johansson has accused OpenAI of deliberately copying her voice for its latest chatbot ‘Sky’. OpenAI said that it would remove the voice, but insisted that it was not meant to be an "imitation" of the star. Lawyer Susan Aslan assesses if the actor has a case, and tech journalist Takara Small updates us on the latest AI releases.
