Truth comes from the collision of different ideas, and theater plays an essential role in showing us that truth, says legendary artistic director Oskar Eustis. In this powerful talk, Eustis outlines his plan to reach (and listen to) people in places across the US where the theater, like many other institutions, has turned its back -- like the deindustrialized Rust Belt. "Our job is to try to hold up a vision to America that shows not only who all of us are individually, but that welds us back into the commonality that we need to be," Eustis says. "That's what the theater is supposed to do."

What happens when technology knows more about us than we do? Poppy Crum studies how we express emotions -- and she suggests the end of the poker face is near, as new tech makes it easy to see the signals that give away how we're feeling. In a talk and demo, she shows how "empathetic technology" can read physical signals like body temperature and the chemical composition of our breath to inform on our emotional state. For better or for worse. "If we recognize the power of becoming technological empaths, we get this opportunity where technology can help us bridge the emotional and cognitive divide," Crum says.

Can technology make people safer from threats like violent extremism, censorship and persecution? In this illuminating talk, technologist Yasmin Green details programs pioneered at Jigsaw (a unit within Alphabet Inc., the collection of companies that also includes Google) to counter radicalization and online harassment -- including a project that could give commenters real-time feedback about how their words might land, which has already increased spaces for dialogue.

"We have to throw our entire selves into building solutions that are as human as the problems they aim to solve."

In a profound talk about technology and power, author and historian Yuval Noah Harari explains the important difference between fascism and nationalism -- and what the consolidation of our data means for the future of democracy. Appearing as a hologram live from Tel Aviv, Harari warns that the greatest danger that now faces liberal democracy is that the revolution in information technology will make dictatorships more efficient and capable of control. "The enemies of liberal democracy hack our feelings of fear and hate and vanity, and then use these feelings to polarize and destroy," Harari says. "It is the responsibility of all of us to get to know our weaknesses and make sure they don't become weapons." (Followed by a brief conversation with TED curator Chris Anderson)

"Local humanitarians have the courage to persist, to dust themselves off from the wreckage and to start again, risking their lives to save others," Hallam says.

Children who live in rural areas can have a hard time getting to the doctor -- much less to an audiologist's clinic for expensive, complex tests to check their hearing.
