Margaret Mitchell: How we can build AI to help humans, not hurt us

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 snapshot in the evolution of artificial intelligence,” Mitchell says. “If we want AI to evolve in a way that helps humans, then we need to define the goals and strategies that enable that path now.”

Laura Galante: How (and why) Russia hacked the US election

Hacking, fake news, information bubbles … all these and more have become part of the vernacular in recent years. But as cyberspace analyst Laura Galante describes in this alarming talk, the real target of anyone looking to influence geopolitics is dastardly simple: it’s you.

Anote Tong at Mission Blue II My country will be underwater soon — unless we work together

For the people of Kiribati, climate change isn’t something to be debated, denied or legislated against — it’s an everyday reality. The low-lying Pacific island nation may soon be underwater, thanks to rising sea levels. In a personal conversation with TED Curator Chris Anderson, Kiribati President Anote Tong discusses his country’s present climate catastrophe and its imperiled future. “In order to deal with climate change, there’s got to be sacrifice. There’s got to be commitment,” he says. “We’ve got to tell people that the world has changed.”

Vivek Maru at TEDGlobal 2017 How to put the power of law in people’s hands

What can you do when the wheels of justice don’t turn fast enough? Or when they don’t turn at all? Vivek Maru is working to transform the relationship between people and law, turning law from an abstraction or threat into something that everyone can understand, use and shape. Instead of relying solely on lawyers, Maru started a global network of community paralegals, or barefoot lawyers, who serve in their own communities and break the law down into simple terms to help people find solutions. Learn more about how this innovative approach to using the law is helping socially excluded people claim their rights. “A little bit of legal empowerment can go a long way,” Maru says.

Heather Lanier at TED@BCG Milan “Good” and “bad” are incomplete stories we tell ourselves

Heather Lanier’s daughter Fiona has Wolf-Hirschhorn syndrome, a genetic condition that results in developmental delays — but that doesn’t make her tragic, angelic or any of the other stereotypes about kids like her. In this talk about the beautiful, complicated, joyful and hard journey of raising a rare girl, Lanier questions our assumptions about what makes a life “good” or “bad,” challenging us to stop fixating on solutions for whatever we deem not normal, and instead to take life as it comes.

JACKSON KATZ: Violence against women — it’s a men’s issue

Domestic violence and sexual abuse are often called “women’s issues.” But in this bold, blunt talk, Jackson Katz points out that these are intrinsically men’s issues — and shows how these violent behaviors are tied to definitions of manhood. A clarion call for us all — women and men — to call out unacceptable behavior and be leaders of change.

A note from Best TEDtalk. #metoo show how everyone is affected by the issue of sexual abuse. And everyone have to be a part of the solution.

MELATI AND ISABEL WIJSEN: Our campaign to ban plastic bags in Bali

Plastic bags are essentially indestructible, yet they’re used and thrown away with reckless abandon. Most end up in the ocean, where they pollute the water and harm marine life; the rest are burned in garbage piles, where they release harmful dioxins into the atmosphere. Melati and Isabel Wijsen are on a mission to stop plastic bags from suffocating their beautiful island home of Bali. Their efforts — including petitions, beach cleanups, even a hunger strike — paid off when they convinced their governor to commit to a plastic bag-free Bali by 2018. “Don’t ever let anyone tell you that you’re too young or you won’t understand,” Isabel says to other aspiring activists. “We’re not telling you it’s going to be easy. We’re telling you it’s going to be worth it.”
