Just weeks before the management shakeup at OpenAI rocked Silicon Valley and made international news, the company's cofounder and chief scientist Ilya Sutskever explored the transformative potential of artificial general intelligence (AGI), highlighting how it could surpass human intelligence and profoundly transform every aspect of life. Hear his take on the promises and perils of AGI — and his optimistic case for how unprecedented collaboration will ensure its safe and beneficial development.

In the US, people spend the overwhelming majority of their time inside buildings that burn fossil fuels, which are bad for both the environment and human health. (Think: breathing in air pollution from gas stoves, furnaces and water heaters.) If we're going to fix this problem, we need to retrofit millions of buildings with all-electric equipment, says energy upgrader Donnel Baird. Hear about his ambitious plan to rip the fossil fuel infrastructure out of aging buildings and upgrade it with smarter, cleaner, healthier technology.

When programmer Tiffani Ashley Bell learned that thousands of people in Detroit were facing water shutoffs because they couldn't afford to pay their bills, she decided to take action -- in the simplest, most obvious way possible. It's an inspiring story of how one person with tenacity and an idea can create monumental change -- and a demonstration that each of us can find our own way to help the world, even if it means starting without all the answers.

We're fast approaching a world where widespread, hyper-realistic deepfakes lead us to dismiss reality, says technologist and human rights advocate Sam Gregory. What happens to democracy when we can't trust what we see? Learn three key steps to protecting our ability to distinguish human from synthetic — and why fortifying our perception of truth is crucial to our AI-infused future.

We can produce abundant, sustainable and cheap energy — for everyone, says physicist Julio Friedmann. He explores the infrastructure, innovation and investment needed to supply energy to 10 billion people, offering case studies from Chile's refurbished supply chain, built in partnership with Japan, to Namibia's budding clean hydrogen production, inviting us to envision a greener, more equitably powered world.

Is it possible that this century is the most important one in human history? The 21st century has already proven to be a period of rapid growth. We're on the cusp of developing new technologies that could entirely change the way people live— and could contribute to unprecedented levels of existential risk. Explore how the decisions we make now might have a major impact on humanity's future. This TED-Ed lesson was directed by Jon Mayes, AIM Creative Studios, narrated by George Zaidan and the music was made by André Aires.

The world has plenty of clean energy. The problem is storing that energy and getting it where we need it, when we need it, says battery recycling pioneer Emma Nehrenheim. While batteries are fundamental to powering a sustainable future, their production is surprisingly harsh on the environment. She lays out the science behind a breakthrough in recycling a battery's core elements, offering a manufacturing solution that could vastly reduce the industry's environmental impact and demand for new materials from mining.

This is an episode we think you might like of Body Electric. TED Radio Hour host Manoush Zomorodi digs into the preliminary results of the listener study with Columbia University researcher Keith Diaz. He shares the surprising — and encouraging — initial findings from more than 20,000 listeners who tried to incorporate movement breaks into their day.

In the multitude of metaverses that exist there are infinite possibilities for inclusivity and creativity. As we revisit a talk that invites us to craft our own digital universes, Minecraft's game director Agnes Larsson shares how the experience of building and sharing metaverses can foster dialogue, friendship and trust — pointing to the meaningful impact virtual worlds can have on the real world. Following the talk, Sherrell explores how these safer metaverses have the power to spill beyond the digital realm and positively impact our entire society.

How do we make historically exclusive fields like classical music, fine arts or academic research more accessible to everyone? Education equalizer and violist Matthew Garcia thinks one way to remove barriers is to create free, virtual education programs that connect talented young minds to the resources they need to thrive in their future careers. Learn more as we revisit this talk about the power of virtual nonprofits to overcome geographic borders and deliver opportunity -- and how you can help every kid reach their dreams.

When it comes to technology, we're often presented with two contrasting visions of the future: one where technology fulfills all our desires, and another where it leads to chaos and conflict. Sociologist Ruha Benjamin is here with a more radical vision of the future — one where humanity isn't saved or slayed by technology, but rather uses it to uplift ordinary people and make things like health care and housing for all a reality. After the talk, Sherrell expands on how tech improves individual lives, and communities at large.

AI won't kill us all — but that doesn't make it trustworthy. Instead of getting distracted by future existential risks, AI ethics researcher Sasha Luccioni thinks we need to focus on the technology's current negative impacts, like emitting carbon, infringing copyrights and spreading biased information. She offers practical solutions to regulate our AI-filled future — so it's inclusive and transparent.
