TED2010 will be our most ambitious yet, seeking out the voices, wherever they are in the world, best placed to help make sense of where we are and to point the way forward. Add extraordinary performances, wondrous art and immersive evening events, and you have a TED experience not to be missed.So what does the world need? Stimulus? Recovery? Sure. But at TED2010 we're digging deeper. We're looking for the core ideas -- and the core values -- that will reinvigorate our quest for a better future. This has taken us to a beautiful plan for the conference. We'll devote each of our 12 main sessions to one key attribute the world needs. And then come at each of them using TED's special outside-the-box multi-disciplinary approach.You can see below how this is shaping up.
