What will happen to us when the internet dies?

And it is dying. At least for us, humans. Our chatter and connection online is being overrun by bots — more than half of online activity is non-human. The internet is on it's way to feeling haunted, like a deserted mall where the fountain is still gurgling, the canned music is still playing, but the people are nowhere to be found. IDEAS explores the dying internet and what we will do when it's dead? If you like this episode, you may want to listen to: We're not machines. Why should our online world define life?

How can we prevent AI from becoming a menace?

There are two things most people agree on — artificial intelligence is rapidly advancing, and the grave risks AI poses are very real — no one, not even ChatGPT, really knows how this will play out. Renowned “Godfather of AI” Geoffrey Hinton argues we need to put the brakes on AI development until we know for sure it can be kept safely under control. Owain Evans is a leading AI researcher and the founder/director of Truthful AI. In his 2025 Hinton lecture series, organized by the AI Safety Foundation, he discusses the risks presented by AI, the means at our disposal to keep it escaping human control, and the challenges of developing coherent, comprehensive strategies to prevent AI from becoming a menace to humankind.

It's time for a 'moral revolution.' This is a call to action

We live in an "age of immorality," argues historian and author Rutger Bregman. "The moral rot runs deep across elite institutions of every stripe," Bregman says in his first BBC Reith Lecture. His series of lectures describes why he is calling for a moral revolution to counter the culture of cynicism and un-seriousness among global elites. Bregman says history has proven how small determined groups have catalysed profound moral change, and that legacy should be an inspirational guide for all of us today. IDEAS is featuring lectures from the BBC Reith Lectures, this is the first episode.

How horses shaped humankind, from inspiring pants to vaccines

Prior to riding horses, no one wore pants. There's a lot to thank horses for in our daily lives. From the Hollywood motion picture to life-saving vaccines for diphtheria and tetanus. Historian Timothy Winegard argues horses are intertwined in our own history to the point that we overlook their importance. His research explains how they shaped societies, economies and cultures. Without us, horses would be nowhere, and vice versa. It was a partnership — our brains and their braun — that truly changed the world. *This episode originally aired on Sept. 10, 2024.

When your grandmother is accused of being a 'fascist spy'

It was a simple honeymoon photo from 1941. A stranger posted it online and the commentary was vicious. The woman in that picture was Albanian author Lea Ypi’s grandmother. In the midst of the Second World War and the violent end times of Mussolini’s government, Ypi’s grandmother must have been a fascist, a collaborator, a traitor to Albania. In her book, Indignity: A Life Reimagined, Ypi attempts to find the truth of her grandmother’s life, in a journey that mixes philosophy, fantasy, history, and family narrative.
