What it’s like to be the child of immigrants | Michael Rain

Michael Rain is on a mission to tell the stories of first-generation immigrants, who have strong ties both to the countries they grew up in and their countries of origin. In a personal talk, he breaks down the mischaracterizations and limited narratives of immigrants and shares the stories of the worlds they belong to. “We’re walking melting pots of culture,” Rain says. “If something in that pot smells new or different to you, don’t turn up your nose. Ask us to share.”

Why fascism is so tempting — and how your data could power it | Yuval Noah Harari

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 Q&A with TED curator Chris Anderson)

How Pakistani women are taking the internet back | Nighat Dad

TED Fellow Nighat Dad studies online harassment, especially as it relates to patriarchal cultures like the one in her small village in Pakistan. She tells the story of how she set up Pakistan’s first cyber harassment helpline, offering support to women who face serious threats online. “Safe access to the internet is access to knowledge, and knowledge is freedom,” she says. “When I fight for a woman’s digital rights, I am fighting for equality.”

The age-old sharing economies of Africa — and why we should scale them | Robert Neuwirth

From rides to homes and beyond, we’re sharing everything these days, with the help of digital tools. But as modern and high-tech as the sharing economy seems, it’s been alive in Africa for centuries, according to author Robert Neuwirth. He shares fascinating examples — like apprenticeships that work like locally generated venture capital and systems for allocating scarce water — and says that if we can propagate and scale these models, they could help communities thrive from the bottom up.

Scientists must be free to learn, to speak and to challenge | Kirsty Duncan

“You do not mess with something so fundamental, so precious, as science,” says Kirsty Duncan, Canada’s first Minister of Science. In a heartfelt, inspiring talk about pushing boundaries, she makes the case that researchers must be free to present uncomfortable truths and challenge the thinking of the day — and that we all have a duty to speak up when we see science being stifled or suppressed.

The doctors, nurses and aid workers rebuilding Syria | Rola Hallam

Local humanitarians are beacons of light in the darkness of war, says humanitarian aid entrepreneur and TED Fellow Rola Hallam. She’s working to help responders on the ground in devastated communities like Syria, where the destruction of health care is being used as a weapon of war. One of her campaigns achieved a global first: a crowdfunded hospital. Since it opened in 2017, the aptly named Hope Hospital has treated thousands of children. “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. “We can match their courage by not looking away or turning our backs.”

A healthy economy should be designed to thrive, not grow | Kate Raworth

What would a sustainable, universally beneficial economy look like? “Like a doughnut,” says Oxford economist Kate Raworth. In a stellar, eye-opening talk, she explains how we can move countries out of the hole — where people are falling short on life’s essentials — and create regenerative, distributive economies that work within the planet’s ecological limits.
