Towering 85 meters above the Norwegian countryside, Mjøstårnet is the world's tallest wooden building, made almost entirely from the trees of neighboring forests. But as recently as the end of the 20th century, engineers thought it was impossible to build a wooden building over 6 stories tall. So how do wooden structures like this compare to ste...

A. Dara Dotz left the tech industry for the nonprofit world after realizing our widespread reliance on tech may be doing us more harm than good. In response, she founded Field Ready to work directly with communities on the ground in disaster zones and co-develop low-tech aid solutions, repurposing found materials like car mats and broken solar p...

A hostile artificial intelligence called NIM has taken over the world's computers. You're the only person skilled enough to shut it down, and you'll only have one chance. Can you survive and shut off the artificial intelligence? Dan Finkel shows how. [TED-Ed Animation by Artrake Studio]

What if you could consult Winston Churchill on a looming international crisis? Or ask Einstein what he thinks about the latest scientific breakthrough? National security expert Juliane Gallina is working on a way to harness the best thinking strategies of all time.

What do you get when you give a design tool a digital nervous system? Computers that improve our ability to think and imagine, and robotic systems that come up with (and build) radical new designs for bridges, cars, drones and much more -- all by themselves. Take a tour of the Augmented Age with futurist Maurice Conti and preview a time when rob...

Meet Todai Robot, an AI project that performed in the top 20 percent of students on the entrance exam for the University of Tokyo -- without actually understanding a thing. While it's not matriculating anytime soon, Todai Robot's success raises alarming questions for the future of human education. How can we help kids excel at the things that hu...

Imagine an extra brain that knows us better than we know ourselves, that exists "with us, beside us, experiencing our world with us ... always connected, always processing, always watching." Nivruti Rai believes that AI systems could become these kinds of guardian angels, if given the chance. In this future-forward talk, Rai explains how machin...

Explore what may be in store for our collective future and how we can plan for the unpredictable, together.

Ray Kurzweil is an engineer who has radically advanced the fields of speech, text and audio technology. He's revered for his dizzying -- yet convincing -- writing on the advance of technology, the limits of biology and the future of the human species.

Joseph Redmon works on the YOLO algorithm, which combines the simple face detection of your phone camera with a cloud-based AI -- in real time.

In 2013, a group of researchers wanted to create an AI system that could beat every Atari game. They developed a system called Deep Q Networks (DQN) and less than two years later, it was superhuman. But there was one notable exception. When playing Montezuma's Revenge, DQN couldn't score a single point. What was it that made this game so vexingl...

Roy Bahat was worried. His company invests in new technology like AI to make businesses more efficient -- but, he wondered, what was AI doing to the people whose jobs might change, go away or become less fulfilling? The question sent him on a two-year research odyssey to discover what motivates people, and why we work. In this conversation with ...

"The actual path of a raindrop as it goes down the valley is unpredictable, but the general direction is inevitable," says digital visionary Kevin Kelly -- and technology is much the same, driven by patterns that are surprising but inevitable. Over the next 20 years, he says, our penchant for making things smarter and smarter will have a profoun...

As a research scientist at Google, Margaret Mitchell helps develop computers that can communicate about what they see and understand. She tells a cautionary tale about the gaps, blind spots and biases we subconsciously encode into AI -- and asks us to consider what the technology we create today will mean for tomorrow. "All that we see now is a ...

Since humanity first imagined the reality of intelligent machines, we've been afraid that they'll overpower us one day. Bruno Michel shares a more optimistic view: by investing in our mental fitness -- through studying Latin, doing yoga or even tap dancing -- we can increase our likelihood of staying competitive with sophisticated AI.

Many diseases are driven by metabolites -- small molecules in your body like fat, glucose and cholesterol -- but we don't know exactly what they are or how they work. Biotech entrepreneur and TED Fellow Leila Pirhaji shares her plan to build an AI-based network to characterize metabolite patterns, better understand how disease develops -- and di...

Try talking to yourself without opening your mouth, by simply saying words internally. What if you could search the internet like that -- and get an answer back? In the first live public demo of his new technology, TED Fellow Arnav Kapur introduces AlterEgo: a wearable AI device with the potential to let you silently talk to and get information ...

As humans we're inherently biased. Sometimes it's explicit and other times it's unconscious, but as we move forward with technology how do we keep our biases out of the algorithms we create? Documentary filmmaker Robin Hauser argues that we need to have a conversation about how AI should be governed and ask who is responsible for overseeing the ...

To futureproof your job against robots and AI, you should learn how to code, brush up on your math skills and crack open an engineering textbook, right? Wrong. In this surprisingly comforting talk, tech journalist Kevin Roose makes the case that rather than trying to compete with the machines, we should instead focus on what makes us uniquely hu...

Onstage at TED2014, Google CEO Larry Page talks about his far-off vision for the company. It includes aerial bikeways and internet balloons ... and then it gets even more interesting, as Page talks through the company's recent acquisition of Deep Mind, an AI that is learning some surprising things.

Jamila Gordon believes in the power of human connection -- and artificial intelligence -- to help people who might otherwise be left behind. Telling the story of her own path from refugee to global tech executive, she shows how AI is helping refugees, migrants and those from disadvantaged backgrounds find jobs and develop the skills they need to...

Scared of superintelligent AI? You should be, says neuroscientist and philosopher Sam Harris -- and not just in some theoretical way. We're going to build superhuman machines, says Harris, but we haven't yet grappled with the problems associated with creating something that may treat us the way we treat ants.

Computers are being taught to learn, reason and recognize emotions. In these talks, look for insights -- as well as warnings.

Jeremy Howard imagines how advanced machine learning can improve our lives.

Dennis Hong is the founder and director of RoMeLa -- a Virginia Tech robotics lab that has pioneered several breakthroughs in robot design and engineering.

How comfortable are you with robots taking over your life? Covering a wide range of potential applications -- from the mundane (robot house cleaner) to the mischievous (robot sex partner) to the downright macabre (uploading your brain to live on after death) -- technology strategist Lucy Farey-Jones shares data-backed evidence of how our willing...

The algorithms we've created to make our lives more organized and less chaotic are also learning from our behavior -- and our biases. Roboticist Ayanna Howard explores ways we can train our tech to be fairer than us, asking: How can we be more accountable in our relationships with robots?

Can a computer crack a joke? Can it even have a sense of humor? For computer engineer and aspiring comedian Vinith Misra, this is not just a curiosity. By analyzing data sets in social media, Misra discovers ways to help us connect with each other, and make our often frustrating relationship with machines funnier and friendlier.

Before the coronavirus pandemic, bioengineer Jim Collins and his team combined the power of AI with synthetic biology in an effort to combat a different looming crisis: antibiotic-resistant superbugs. Collins explains how they pivoted their efforts to begin developing a series of tools and antiviral compounds to help fight COVID-19 -- and shares...

Land restoration is about more than planting trees, says environmentalist Susan Graham. Check out how her team combines drone technology with ecology-trained AI to restore degraded land and revive complex, biodiverse ecosystems -- whether it's on a small island or across an entire continent.
