Ways to Change the World with Krishnan Guru-Murthy

Artificial intelligence is evolving faster than ever - and the debate over AI safety, regulation, and control is intensifying. 
In this episode of Ways to Change the World, Krishnan Guru-Murthy speaks to Jack Clark, co-founder and Head of Policy at Anthropic, the company behind the Claude AI systems. A former journalist turned AI insider, Clark has been at the centre of some of the biggest debates shaping the future of this technology - from safety and regulation to the race between innovation and control.
They discuss Clark’s journey from reporting on AI to building it, his decision to leave OpenAI over concerns about safety, and the growing fear that powerful systems are outpacing our ability to manage them. From warning governments at the UN to grappling with the risks as a father, Clark reflects on the tension at the heart of his work: what does it mean to build something you believe could be dangerous?

Prue Leith may be best known as a judge on The Great British Bake Off, but her influence reaches far beyond television. She founded a leading cookery school, built a Michelin-starred restaurant, spent decades shaping national policy on food education and public health, and has written extensively on ageing. This year she also served as a judge for The British Book Awards.

In this episode of Ways to Change the World, she speaks to Krishnan Guru-Murthy, reflecting on her latest new book ‘Being Old… and Learning to Love It!’ and talks frankly about growing older, staying relevant, finding happiness, and why she believes ageing can be liberating. Prue also discusses childhood nutrition, school food, her campaigns with Jamie Oliver, weight-loss injections, why she refuses to exercise, and the realities of caring for a parent with dementia.
This conversation includes discussion around suicide.

Amanda Knox became internationally known following the 2007 murder of Meredith Kercher in Pereugia, Italy, and the years of legal proceedings and media scrutiny that followed. Knox was found guilty of Meredith’s murder in 2009 but was ultimately acquitted in 2015.
She has since written and spoken extensively about her experience, and has advocated for others who may have been falsely imprisoned. Her latest documentary, Mouth of the Wolf, sees her return to Perugia, where she spent four years in prison - and confront Giuliano Mignini, the prosecutor who sent her to prison more than 15 years ago.
In this episode of Ways to Change the World, Krishnan Guru-Murthy speaks to Knox about accountability in the justice system, the importance of admitting when institutions get it wrong, and the lasting stigma that follows even after innocence is proven.

Heston Blumenthal is one of the world’s most innovative chefs, known for transforming the way we think about food, flavour and the dining experience. From his self-taught beginnings to building one of the most celebrated restaurants in the world, his career has been defined by curiosity, experimentation and a refusal to follow convention. But beyond the kitchen, Blumenthal has also been navigating deeply personal mental health challenges that almost led him to death at one point. 
In 2023, Heston was sectioned after his wife called medical professionals following a severe manic episode and bipolar diagnosis.

On this episode of Ways to Change the World, Krishnan Guru-Murthy speaks to Heston Blumenthal about his approach to mindful and sustainable eating, living with ADHD and bipolar disorder, and why he is determined to challenge stigma.

My guest this week is Eric Schlosser, the investigative journalist and author whose work has fundamentally changed how we think about what we eat. Fast Food Nation was a landmark book that exposed the abuse of animals and the exploitation of workers at the heart of America's food industry. 
Now, 25 years after it was first published, Schlosser says he is astonished that not only has the industry failed to improve, in many ways it has gotten worse. And yet, despite this, he still believes change is possible.
