In this episode, we talk to Sarah Wilson. She’s had an incredibly diverse career - from teenage model, to newspaper columnist, to women’s magazine editor, and then best-selling author of the book, I Quit Sugar, in 2012. More books followed, on anxiety, and finding purpose in a disconnected world, especially through the climate change crisis. Now she’s focused on cascading and wicked problems - such as climate change, inequality, artificial intelligence and political polarisation - that will lead to nothing less than the collapse of civilisation. But she also thinks there might just be an upside. Wilson is the subject of our cover story this week - THE CRUSADER - and hosting our conversation today is the journalist behind that profile, Good Weekend senior writer Gay Alcorn.
