In an astonishing talk and tech demo, neurotechnologist Conor Russomanno shares his work building brain-computer interfaces that could enable us to control the external world with our minds. He discusses the quickly advancing possibilities of this field -- including the promise of a "closed-loop system" that could both record and stimulate brain activity -- and invites neurohacker Christian Bayerlein onto the TED stage to fly a mind-controlled drone by using a biosensing headset.

Computer scientist Yejin Choi is here to demystify the current state of massive artificial intelligence systems like ChatGPT, highlighting three key problems with cutting-edge large language models (including some funny instances of them failing at basic commonsense reasoning.) She welcomes us into a new era in which AI is becoming almost like a new intellectual species -- and identifies the benefits of building smaller AI systems trained on human norms and values. (Followed by a Q&A with head of TED Chris Anderson)

Is AI as smart as it seems? Exploring the "brain" behind machine learning, neural networker Alona Fyshe delves into the language processing abilities of talkative tech (like the groundbreaking chatbot and internet obsession ChatGPT) and explains how different it is from your own brain -- even though it can sound convincingly human.

To restrain global warming, we know we need to drastically reduce pollution. The very next step after that: using both natural and technological solutions to trap as much excess carbon dioxide from the air as possible. Enter Orca, the world's first large-scale direct air capture and storage plant, built in Iceland by the team at Climeworks, led by climate entrepreneur Jan Wurzbacher. This plant is capable of removing 4,000 tons of carbon dioxide from the air each year. With affordability and scalability in mind, Wurzbacher shares his vision for what comes after Orca, the future of carbon removal tech -- and why these innovations are crucial to stop climate change.

After a billion years of evolution, fungi are masters of invention and resilience. What wisdom can we draw from their long, remarkable existence? Mycologist David Andrew Quist explores how fungi's innate biointelligence, penchant for collaboration and incredible regeneration abilities can show us new ways to think about complex problems -- and may hold the secret to humanity's survival on Earth.

Indigenous wisdom can help solve the planetary crises that colonialism started, says lawyer Jennifer "Jing" Corpuz. Her ancestors, the Kankanaey-Igorot people of the Philippines, are known for creating the Banaue Rice Terraces: centuries-old irrigated mountain terraces that illustrate the magic of humanity living in harmony with nature. Corpuz shares five values that have guided her people as they successfully fought against development aggression and invites everyone to pursue a more just, sustainable world.

Are insects the key to brain-inspired computing? Neuroscientist Frances S. Chance thinks so. In this buzzy talk, she shares examples of the incredible capabilities of insects -- like the dragonfly's deadly accurate hunting skills and the African dung beetle's superstrength -- and shows how untangling the mysterious web of neurons in their tiny brains could lead to breakthroughs in computers, AI and more.

Remote work, while redefining the workplace landscape, seems stuck behind endless video conference calls that hinder free-flowing conversation and collaboration. In the 21st century, is that really the best we can do? Digital anthropologist Josephine Eyre makes the case for embracing the metaverse as an immersive meeting place that could help reignite creativity and communication.

Imagine a boat that propels by moving its "tail" from side to side, just like a fish. That's the kind of machine that TED Fellow Robert Katzschmann's lab builds: soft-bodied robots that imitate natural movements with artificial, silent muscles. He lays out his vision for machines that take on mesmerizing new forms, made of softer and more lifelike materials -- and capable of discovering unknown parts of the world.

We're going to be building on the Moon this decade -- and next will be Mars, says space architect Melodie Yashar. In a visionary talk, she introduces her work designing off-world shelters with autonomous robots and 3D printers and explores how it might help uncover radical solutions to some of the problems troubling humans on Earth today.
