"Will you forgive me?" asks community leader Sean Goode. He proposes that the promise of forgiveness before wrongdoing — what he calls "unapologetic grace" — can empower people to share their truths and create space to bridge our differences.

From synthetic embryos to lab-grown skin, we live in a brave new world of stem cell advances. So why can it still take years to recover from injury? Orthopedic surgeon Kevin Stone is working to accelerate the body's healing response so you could recover in a matter of days or weeks, not months or years.

As humans live longer than ever before, we need our implants to last as long as we do, says bioengineer Nina Tandon. Using stem cells and digital fabrication, she's working on growing anatomically precise spare parts for the human body, replacing damaged bones, cartilage and more with implants that fit perfectly and hold up for a lifetime.

As the cofounder of Google DeepMind, Shane Legg is driving one of the greatest transformations in history: the development of artificial general intelligence (AGI). He envisions a system with human-like intelligence that would be exponentially smarter than today's AI, with limitless possibilities and applications. In conversation with head of TED Chris Anderson, Legg explores the evolution of AGI, what the world might look like when it arrives — and how to ensure it's built safely and ethically.

"The world's most important advanced technology is nearly all produced in a single facility," says AI expert Rob Toews. He describes how one company in Taiwan, TSMC, manufactures nearly all the most advanced semiconductor chips — a crucial technology that powers everything from phones to electric vehicles to next-generation artificial intelligence — and breaks down how geopolitical tensions in the region could paralyze the global field of AI.

AI could propel the biggest transformation in the history of medicine, says physician-scientist Eric Topol. He explains how sophisticated AI models can interpret medical images as well or better than human experts can — and, beyond that, even pick up things that human eyes can't see. Learn all the ways AI is poised to make a difference for both patients and doctors.

Generative AI is poised to transform the workplace, but we still need human brains for new ideas, says marketing expert Jessica Apotheker.

Clearing tropical forests isn't just dangerous to the natural world — it's also a threat to human health and wellbeing, says physician Neil Vora. Tracing how environmental devastation led to deadly epidemics like Ebola, he presents three ways deforestation unleashes disease and calls on each of us to help preserve the delicate ecological balance we depend upon.

South Africa transitioned to democracy in the 1990s with a visionary constitution, but the promises of that constitution are largely unfulfilled to this day. Public leader Lindiwe Mazibuko explores how poor leadership failed to deliver a better life for the country's citizens — and shares her mission to cultivate a new generation of ethical leaders who can revitalize democracy in South Africa and beyond.

Tackling climate change costs a lot of money — and the financial sector is key to getting that money flowing. In a wide-ranging conversation, sustainable investment leaders Nili Gilbert and David Blood discuss where progress is being made on climate solutions, where capital still needs to move faster and why this is an unprecedented opportunity for sustainable growth.

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.

Photosynthesis is one of the most important processes on the planet, helping produce the food we eat and the air we breathe. Crop scientist Steve Long thinks it could be more efficient — and he's intent on giving it a boost. He shows how hacking photosynthesis could help feed the world all while reducing climate change.
