Two-time Pulitzer finalist on the scientist who won the Nobel Prize and may not be able to stop what he started.
What if the person trying to make artificial intelligence safe is also one of the people racing to build it?
In this episode of High Net Purpose, Joe McCarthy sits down with Sebastian Mallaby, bestselling author and two-time Pulitzer Prize finalist, whose latest book explores Demis Hassabis, Google DeepMind and the quest for superintelligence.
Over the course of the conversation, Sebastian unpacks the extraordinary story behind DeepMind: why it was built in London, how Demis held onto a mission formed in childhood, and why the race for AI sits at the intersection of science, ambition, safety and power.
From AlphaGo’s victory over Lee Sedol to the battle for AI safety oversight inside Google, this is a conversation about what happens when human purpose meets machine intelligence. It asks whether AI will deepen human potential, undermine it, or force us to redefine what purpose means altogether.
Along the way, we explore the role of founders, family offices and capital allocators in a world where the technology changes faster than the rules around it.
This is the story of the AI paradox, and the man trying to understand the people building the future.
