A bowl of spinach in 1911 held the nutrients of eleven bowls today. Ian Khan visits Star Walker Organic Farms in northern California, home of the first regenerative organic certified beef in the US and pork in the world, to see 7,000 acres farmed by rotational grazing, compost and closed loops, and to ask whether the future of food is built to outsmart nature or to work with it.

Robotics drew nearly 38 billion dollars of investment in 2025, and physical AI is where intelligence leaves the screen and takes a body. Ian Khan sits down with NVIDIA’s robotics leadership and the founders of Humanoid to unpack the three-computer platform behind robot brains, what working humanoids already do in industrial sites, and why the real opportunity now lies in deployment, safety and the workforce transition around them.

Every second, the world’s machines make a billion decisions no human will review. Ian Khan goes to the front line of four fights happening at once: a physicist trying to see inside an alien intelligence we grew rather than built, a builder racing to power data centres the size of city blocks, a hacker turned guardian defending encryption against the quantum threat, and a neuroscience lab where a brain-computer interface helped a child who could not move. Four fights, one question: what are we becoming?

A pizza made start to finish by robots at an airport is the newest link in a century-long chain. Ian Khan follows how growing, harvesting, moving and serving food were each automated in turn, visits Donatos to see how a family pizza tradition is being protected with robotic kitchens, and looks 25 years ahead: autonomous last-mile delivery, round-the-clock robot kitchens, and the hard economic lessons of vertical farming.

Diagnostic imaging informs nearly 80% of clinical decisions in hospital care, and AI is rewriting how it works. Ian Khan sits down with the team at Philips to see how artificial intelligence is making MRI, CT and ultrasound faster, sharper and smarter: catching cancers earlier, reading scans in seconds and closing gaps in care that have existed for decades. Philips’ Future Health Index, a survey of 1,900 clinicians and 16,000 patients in 16 countries, finds clinicians 79% optimistic about AI against 59% of patients, and the episode asks what it will take to close that gap while giving doctors and nurses their time, and the joy of their practice, back.
