TED Tech

When technologist Luis von Ahn was building the popular language-learning platform Duolingo, he faced a big problem: Could an app designed to teach you something ever compete with addictive platforms like Instagram and TikTok? He explains how Duolingo harnesses the psychological techniques of social media and mobile games to get you excited to learn — all while spreading access to education across the world.

What if you could control your digital devices using just the power of thought? That's the incredible promise behind the Stentrode — an implantable brain-computer interface that collects and wirelessly transmits information directly from the brain, without the need for open surgery. Neurotech entrepreneur Tom Oxley describes the intricacies of this breakthrough technology, which is currently enrolling participants in human trials, as well as how it could help restore dignity to those with disabilities — and transform the future of communication. Stay tuned after the talk to hear our host Sherrell talk about the promise and potential of technology when it comes to serving one of humanity's greatest needs: connection.

From exoskeletons and robotic arms to the mass adoption of remote work, economist Piyachart Phiromswad explores what seniors need to overcome the physical, mental and societal barriers to employment, a necessary shift in our rapidly aging world. Learn more about how these tools could empower elderly workers and better the world — for everyone. After the talk, Sherrell explores the ethical considerations of keeping aging populations in the workforce for the sake of productivity.

This is an episode of Fixable, another podcast from the TED Audio Collective. This week, Anne and Frances dive into their area of expertise: trust. Frances recounts the time when she was brought in to help Uber fix their huge trust breakdown. Using Uber as a case study, they explain the three pillars of trust — authenticity, empathy and logic — and actionable solutions to strengthen each leg when they’re on shaky ground.

“AI can be a transformational tool in our fight against climate change," says Sims Witherspoon, a leader at the AI research lab Google DeepMind. Using wind power as her case study, she explains how powerful neural networks can help us better predict Earth's changing ecosystems and accelerate the breakthrough science needed to create a carbon-free energy supply.

From health-tracking wearables to smartphones and beyond, data collection and computer modeling have become a ubiquitous part of everyday life. Advancements in these areas have given birth to "digital twins," or virtual models that evolve alongside real-world data. Aerospace engineer Karen Willcox explores the incredible possibilities these systems offer across engineering, climate studies and medicine, sharing how they could lead to personalized medicine, better decision-making and more.

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.

Lethal drones with facial recognition, armed robots, autonomous fighter jets: we're at the dawn of a new age of AI-powered warfare, says technologist Alexandr Wang. He explores why data will be the secret weapon in this uncharted landscape and emphasizes the need to consider national security when developing new tech — or potentially face all-out AI warfare.

What if we could hear nature's ultrasonic communication -- and talk back? From a bat's shrill speech to a peacock's infrasound mating call, conservation technology researcher Karen Bakker takes us through a sound bath of animal noises that are far outside humanity's range of hearing, demonstrating how artificial intelligence has translated the incredible complexity of nature's soundtrack. She asks us to consider the moral weight of such transformative technology and explores the futuristic opportunities presented for conservation, interspecies communication and more. The TED team is saddened to share that Karen Bakker passed away in August 2023. We’re grateful for the opportunity to uplift her work.

Megafires, or fires that burn more than 100,000 acres, are becoming more frequent worldwide, wreaking havoc on landscapes and communities -- and fire experts say the problem is only going to get worse. George T. Whitesides is focused on fighting these devastating natural disasters through innovative technologies and intentional changes to how we build communities. He presents three emerging solutions to this blazing dilemma, calling for us to redefine our relationship with fire in order to build a more resilient and sustainable future. After the talk, Sherrell highlights the importance of looking to Indigenous practices when it comes to curbing wildfires.

This is an episode of Body Electric a series airing over at the TED Radio Hour. In this special series, host Manoush Zomorodi investigates the relationship between our technology and our bodies and asks: How are we physically adapting to meet the demands of the Information Age? Why do so many of us feel utterly drained after a day spent attached to our devices? Part one kicks off with an exploration into how economic eras have shaped the human body in the past with author Vybarr Cregan-Reid. Then, Columbia University researcher and exercise physiologist Keith Diaz and Manoush discuss his findings and propose a challenge to listeners: Let's see if we can end this cycle of type, tap, collapse together.

We’ve got a special 6-part series with an interactive twist coming your way: On Body Electric, TED Radio Hour host Manoush Zomorodi investigates the relationship between our bodies and our technology…and she has a challenge for YOU. Starts Tuesday, October 3rd

Will truth and reason survive the evolution of artificial intelligence? AI researcher Gary Marcus says no, not if untrustworthy technology continues to be integrated into our lives at such dangerously high speeds. He advocates for an urgent reevaluation of whether we're building reliable systems (or misinformation machines), explores the failures of today's AI and calls for a global, nonprofit organization to regulate the tech for the sake of democracy and our collective future. (Followed by a Q&A with head of TED Chris Anderson)

In the last few decades, China has gone from technological scarcity to abundance. What sparked this shift? Economist Keyu Jin explores how China has fostered a model of innovation unlike any other and shows why understanding its competitive, collaborative approach could benefit the world -- and perhaps demystify some contradictions.

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.
