In 1998, she says, “I was Patient Zero of losing a personal reputation on a global scale almost instantaneously.” Today, the kind of online public shaming she went through has become constant -- and can turn deadly. In a brave talk, she takes a hard look at our online culture of humiliation, and asks for a different way.

Esplora il contenutoIn a robot lab at TEDGlobal, Raffaello D'Andrea demos his flying quadcopters: robots that think like athletes, solving physical problems with algorithms that help them learn. In a series of nifty demos, D'Andrea show drones that play catch, balance and make decisions together -- and watch out for an I-want-this-now demo of Kinect-controlled quads.

She tells the story of her metamorphosis -- from a wide-eyed teenager soaking in verse at New York's Bowery Poetry Club to a teacher connecting kids with the power of self-expression through Project V.O.I.C.E. -- and gives two breathtaking performances of "B" and "Hiroshima."

Esplora il contenutoTim Urban knows that procrastination doesn't make sense, but he's never been able to shake his habit of waiting until the last minute to get things done. In this hilarious and insightful talk, Urban takes us on a journey through YouTube binges, Wikipedia rabbit holes and bouts of staring out the window -- and encourages us to think harder about what we're really procrastinating on, before we run out of time.
