AI in warfare is no longer hypothetical; it's inevitable, says Palmer Luckey, an inventor and founder of the defense technology company Anduril Industries. He takes us inside the high-tech arms race to build AI-powered weapons, "killer robots" and autonomous fighter jets at scale — and makes the counterintuitive case for why this may be the surest path to deterrence and lasting peace. (Followed by Q&A with technologist Bilawal Sidhu)

"If you can't respect the basic fundamental underlying principles with which we order society — which is 'Do not steal' — then what are you left with?" asks investigative journalist Carole Cadwalladr. Following her TED2025 talk, Cadwalladr is in conversation with Chris Anderson, head of TED, to warn about surveillance fascism. What happens when big Silicon Valley companies take over communication platforms and weaponize intellectual property against you? She suggests that when you feel powerless, it's often actually because you are powerful — and explores why it's so important to fight information chaos by supporting independent media and journalists.

Can art pave the way for a politically divided nation to move forward? Artist, cultural strategist and TED Fellow Marc Bamuthi Joseph reflects on the role of art, forgiveness and remembrance in the pursuit of public healing — especially at a time when trust is contested and community forums fractured. Wendy Whelan, associate artistic director of the New York City Ballet, joins him on stage for a rendition of “The Carnival of the Animals,” exploring how the cuckoo bird exemplifies the cycles of inaction that lead to injustice. It's more than a performance — it's a reckoning.

Hope isn’t just a feeling, but a skill you can practice, explains climate activist Xiye Bastida. Taking cues from the resilience of nature, she shows why trusting Indigenous leaders who’ve protected the planet for generations can help turn despair about the climate into the momentum needed to ignite meaningful change. A powerful reminder that the fire in your heart is your greatest strength for creating a better future.

Picture this: you’re wearing a normal-looking pair of glasses, but they give you the ability to quickly summarize a book, translate between languages or remember where you left your keys. In a live demo of unreleased technology, computer scientist Shahram Izadi unveils Google’s new Android XR platform, which aims to give users the power of AI via smart glasses and headsets. He’s joined onstage by two colleagues, giving a glimpse of the future of “extended reality” (XR) devices — smart, seamless and right before your eyes.

What if the race to save the planet is harming the people who protect it? Indigenous advocate Galina Angarova exposes the hidden cost of the green energy transition, where the demand for minerals like nickel and lithium threatens to devastate Indigenous lands and livelihoods.

“We are watching the collapse of the international order in real time, and this is just the start,” says investigative journalist Carole Cadwalladr. In a searing talk, she decries the rise of the “broligarchy” — the powerful tech executives who are using their global digital platforms to amass unprecedented geopolitical power, dismantling democracy and enabling authoritarian control across the world. Her rallying cry: resist data harvesting and mass surveillance, and support others in a groundswell of digital disobedience. “You have more power than you think,” she says. (This talk contains mature language.)

There's an invisible super-pollutant heating up the planet — but it's surprisingly easy to reduce, if we try. Revealing how methane contributes (way) more in the short term to global warming than carbon dioxide, chemical engineer Daniel Zavala-Araiza highlights the emerging technologies and bold new policies that are part of a worldwide effort to hold oil and gas companies accountable for polluting our skies with this harmful gas. It's an optimistic glimpse into a future where global cooperation and cutting-edge monitoring could rapidly slow climate change.

Today's experts often overwhelm parents and guardians with alarming warnings of treacherous roads ahead for their children, sometimes turning dedication into anxiety and obsessiveness.

Join Hazel as she prepares and delivers her big idea in a TED Talk — and gets some surprising news that just might bring puddle parks to life.

If you’ve ever wondered how you can give a TED Talk, you’re not alone. TED believes that ideas change everything — and that they can come from unexpected places. So, we issued an open call to anyone in the UK in search of the biggest, boldest and brightest ideas. Out of 500 applicants, 10 were selected to speak at a special in-person TED event in partnership with TEDxBrighton. In this film, you’ll meet all 10 speakers and follow the process of going from an idea in someone's head to an actual TED Talk on the stage. We’re always looking for the next big idea — maybe yours could be next.

Change leader Kristy Ellmer shares a powerful lesson on how even the most difficult transitions, including layoffs and company-wide transformations, can open unexpected doors. She offers tools from behavioral science to help you shift your mindset and navigate uncertainty with confidence — even when every instinct tells you to resist.

It's easy to say you have values — but how can you actually put them into action? Ethicist and rabbi Ira Bedzow helps people wrestle with this big question so they can navigate life with a sense of meaning and direction. He sits down with Shoshana Ungerleider, physician and host of the "TED Health" podcast, to discuss why you may have more than one singular purpose, how to define success on your own terms and the role of community in a fulfilling life.

Would you rather stay in your current job until you retire, or change jobs every year? Researcher Amanda Schneider says Gen Z's answer to this question says a lot about the evolving workplace. Sharing data-driven insights on the young workforce, she debunks common misconceptions about Gen Z employees and explains why their preferences are key to unlocking a more flexible, effective workplace for everyone.

Cement is one of the most-consumed materials on Earth — second only to water — and it accounts for a whopping eight percent of the world's carbon pollution. What if we could turn this climate villain into a hero? Clean tech innovator and serial entrepreneur Ryan Gilliam reveals his company's surprisingly simple process for transforming waste from the cement-making process back into limestone using existing infrastructure, creating a competitive and eco-friendly product that could pave the way for gigaton-scale climate solutions.

Leo Villareal is an artist, but his tools aren't paint and canvas; he manipulates light, color and computer code to create monumental works of public art. In a dazzling talk, he takes us inside his efforts to light up some of the world's most iconic bridges — including an installation of 25,000 LED lights on San Francisco's Bay Bridge and a piece uniting nine bridges along London's River Thames — and shows how public art can transform a city.

Self-love isn’t self-indulgence — it’s the learnable skill of treating yourself with the kindness you'd offer a friend, says mindfulness expert Dan Harris.

It’s a spark of optimism for anyone looking to replace empty gestures with thoughtful, practical solutions that actually make a difference. (Created in collaboration with Ignite Talks)

Generative AI is built on three key resources: people, compute and data. While companies invest heavily in the first two, they often use unlicensed creative work as training data without permission or payment — a practice that pits AI against the very creators it relies on. AI expert Ed Newton-Rex has a solution: licensing. He unpacks the dark side of today's AI models and outlines a plan to ensure that both AI companies and creators can thrive together.

Headlines have been swirling as President Trump enters his second month back in office and his policies come into focus.

From Edo Japan’s circular economy to the peaceful coexistence of cultures in medieval Spain, he reveals why looking backward can actually help us move forward.

It lurks within, emerging in conversation to share ineffective, premature suggestions … it’s your advice monster, and we all have one, says writer and teacher Michael Bungay Stanier. He shares how giving advice can easily go astray, from solving the wrong problem to disempowering the very person you’re trying to help, and offers a simple question to help you stay curious, strengthen your relationships — and tame that monster.

Could the key to a sustainable food system already be growing in the world’s farms? Plant scientist Giles E.D. Oldroyd explores how a special quirk of soybean plants allows them to naturally partner with networks of fungi and bacteria to access essential nutrients in the air and soil — eliminating the need for synthetic fertilizers. He shows how harnessing these microscopic powerhouses could help scientists rewire crops to make their own fertilizer, reducing pollution, increasing yields and improving livelihoods for smallholder farmers.
