The Interface is your weekly guide to the tech rewiring your week and your world. Hosted by journalists Thomas Germain, Nicky Woolf, and Karen Hao, each episode unpacks, week by week, how technology is shaping all our futures. No guests. No jargon. Just three sharp voices debating the stories that matter - whether they shook a government, broke the internet, or quietly tipped the balance of power.

In this episode, Tom and Nicky head deep into the TikTok Farlands - the semi mythical place you supposedly reach if you scroll too far, too late, until your feed stops looking normal and starts serving up surreal, eerie and deeply unhinged videos. The name comes from Minecraft’s Far Lands, the glitched edge of the map where the world used to break apart, and TikTok users have borrowed it to describe the “end of the algorithm”: a strange zone of distorted edits, ominous warnings, weirdcore imagery and recurring figures like the now iconic fat bee playing the violin. TikTok’s Farlands have become a shorthand for what happens when doomscrolling tips into digital folklore.

But the Farlands aren’t just a joke. Tom and Nicky ask what this trend says about internet culture now. In a platform ecosystem dominated by polish, branding and optimisation, the Farlands feel like the return of an older internet: raw, surreal, handmade and proudly bizarre. At the same time, the meme also works as a critique of doomscrolling itself — turning algorithmic exhaustion into shared mythology, and making people newly conscious of how deep into the feed they’ve wandered.

So in this episode, we ask: is the TikTok Farlands a genuine return of weird, creative internet culture — or just another algorithmic genre?

Also in this episode: Karen looks at how AI detection tools may be changing the way we all write. As detectors spread through schools, publishing and professional life, students, teachers and writers are increasingly shaping their prose around what software might flag - dropping stylistic quirks, sanding off rhythm, and checking their own work in advance for fear of a false accusation. Researchers say the central problem is not just whether detectors catch AI, but how they balance false positives and false negatives in high stakes settings. And with a growing parallel market of “humanizer” tools promising to make AI text sound more human - and pass detection - the result may be an arms race that leaves everyone writing in a flatter, safer and more paranoid style.

For three years a brutal civil war has been raging in Sudan. Hundreds of thousands have been killed. Millions have been forced from their homes. But the war has other hidden costs – particularly for the young. It’s estimated that 60% of the population is under 25, and millions have lost out on their education. Now after the capital Khartoum was recaptured by the army, for the first time in years, school and universities have re-opened in the city. But as Mohanad Hashim reports, the lives of Khartoum’s youth are still shaped by war.

Renowned Danish chef Trine Hahnemann tells Sahar Zand how she combines the concept of hygge with her cooking. Hygge is a word that is embedded in the Danish language. It’s about relaxing and taking time away from the daily rush to enjoy life's quieter pleasures. And yet, Trine finds the time to write cookery books (over 20 so far), and run cookery lessons from the kitchen in her family home in Copenhagen. She tells Sahar how she does it, as she prepares a comforting meal of freshly harvested vegetables, and explains how she started her culinary career by cooking for rock stars on tour, including Red Hot Chilli Peppers, The Rolling Stones and Elton John.

Potatoes are having a moment. Once dismissed as dull, stodgy or even unhealthy, they are now back, appearing on restaurant menus, in food magazines and across social media feeds. But the story of the potato goes back much further. Ruth Alexander traces the journey of one of the world’s most familiar foods. From its origins millions of years ago to its place in today’s global food system. AJ Shehata, senior sous chef at Fallow restaurant in London explains why the potato forces chefs to get creative. At the Natural History Museum, botanist Sandy Knapp explains how the potato may have been born from a chance encounter between two wild plants in the Andes, an event that made it possible for potatoes to grow underground and spread across new environments. Potatoes USA president Blair Richardson explains how demand continues to grow worldwide, and how the industry is working to reshape the potato’s image. Nutrition scientist Candida Rebello shares research suggesting potatoes may be far more beneficial, and more misunderstood, than many people think. And, at the International Potato Centre in Peru, scientist Julian Soto works with farmers to conserve thousands of native potato varieties. In the Andes, potatoes are not just a crop, they are part of culture, identity and family life.
