Jaron Lanier How we need to remake the internet
In the early days of digital culture, Jaron Lanier helped craft a vision for the internet as public commons where humanity could share its knowledge — but even then, this vision was haunted by the dark side of how it could turn out: with personal devices that control our lives, monitor our data and feed us stimuli. (Sound familiar?) In this visionary talk, Lanier reflects on a "globally tragic, astoundingly ridiculous mistake" companies like Google and Facebook made at the foundation of digital culture — and how we can undo it. "We cannot have a society in which, if two people wish to communicate, the only way that can happen is if it's financed by a third person who wishes to manipulate them," he says.
Kate Raworth A healthy economy should be designed to thrive, not grow
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.
Steven Pinker Is the world getting better or worse? A look at the numbers
Was 2017 really the "worst year ever," as some would have us believe? In his analysis of recent data on homicide, war, poverty, pollution and more, psychologist Steven Pinker finds that we're doing better now in every one of them when compared with 30 years ago. But progress isn't inevitable, and it doesn't mean everything gets better for everyone all the time, Pinker says. Instead, progress is problem-solving, and we should look at things like climate change and nuclear war as problems to be solved, not apocalypses in waiting. "We will never have a perfect world, and it would be dangerous to seek one," he says. "But there's no limit to the betterments we can attain if we continue to apply knowledge to enhance human flourishing."
Will MacAskill What are the most important moral problems of our time?
Of all the problems facing humanity, which should we focus on solving first? In a compelling talk about how to make the world better, moral philosopher Will MacAskill provides a framework for answering this question based on the philosophy of "effective altruism" — and shares ideas for taking on three pressing global issues.
Robin Steinberg What if we ended the injustice of bail?
On any given night, more than 450,000 people in the United States are locked up in jail simply because they don't have enough money to pay bail. The sums in question are often around $500: easy for some to pay, impossible for others. This has real human consequences — people lose jobs, homes and lives, and it drives racial disparities in the legal system. Robin Steinberg has a bold idea to change this. In this powerful talk, she outlines the plan for The Bail Project — an unprecedented national revolving bail fund to fight mass incarceration. (This ambitious idea is part of the Audacious Project, TED's initiative to inspire and fund global change.)
Özlem Cekic Why I have coffee with people who send me hate mail
Özlem Cekic's email inbox has been full of hate mail since 2007, when she won a seat in the Danish Parliament — becoming the first female Muslim to do so. At first she just deleted the emails, dismissing them as the work of fanatics, until one day a friend made an unexpected suggestion: to reach out to the hate mail writers and invite them to meet for coffee. Hundreds of "dialogue coffee" meetings later, Cekic shares how face-to-face conversation can be one of the most powerful forces to disarm hate — and challenges us all to engage with people we disagree with.
Zachary R. Wood Why it's worth listening to people you disagree with
We get stronger, not weaker, by engaging with ideas and people we disagree with, says Zachary R. Wood. In an important talk about finding common ground, Wood makes the case that we can build empathy and gain understanding by engaging tactfully and thoughtfully with controversial ideas and unfamiliar perspectives. "Tuning out opposing viewpoints doesn't make them go away," Wood says. "To achieve progress in the face of adversity, we need a genuine commitment to gaining a deeper understanding of humanity."
Stephen Webb Where are all the aliens?
The universe is incredibly old, astoundingly vast and populated by trillions of planets — so where are all the aliens? Astronomer Stephen Webb has an explanation: we're alone in the universe. In a mind-expanding talk, he spells out the remarkable barriers a planet would need to clear in order to host an extraterrestrial civilization — and makes a case for the beauty of our potential cosmic loneliness. "The silence of the universe is shouting, 'We're the creatures who got lucky,'" Webb says.
Karen J. Meech The story of 'Oumuamua, the first visitor from another star system
In October 2017, astrobiologist Karen J. Meech got the call every astronomer waits for: NASA had spotted the very first visitor from another star system. The interstellar comet — a half-mile-long object eventually named `Oumuamua, from the Hawaiian for "scout" or "messenger" — raised intriguing questions: Was it a chunk of rocky debris from a new star system, shredded material from a supernova explosion, evidence of alien technology or something else altogether? In this riveting talk, Meech tells the story of how her team raced against the clock to find answers about this unexpected gift from afar.
Kai-Fu Lee How AI can save our humanity
AI is massively transforming our world, but there's one thing it cannot do: love. In a visionary talk, computer scientist Kai-Fu Lee details how the US and China are driving a deep learning revolution — and shares a blueprint for how humans can thrive in the age of AI by harnessing compassion and creativity. "AI is serendipity," Lee says. "It is here to liberate us from routine jobs, and it is here to remind us what it is that makes us human."
