AI and the paradox of self-replacing workers

There's a reliable indicator of a woman's future likelihood of cardiovascular disease — but it rarely gets asked about, says obstetrician and researcher Meryam Sugulle. She delves into the role of the placenta in pregnancy, how it can predict health outcomes and the single question that should be worked into routine health screenings.

Here's a conundrum: the same aerosol pollutants that harm human health also help cool the climate, says atmospheric scientist Sarah J. Doherty. Is there a way to clean up the air without warming the planet? Exploring the unintended consequences of reducing air pollution, she makes the case for a better understanding of marine cloud brightening — or intentionally adding sea salt aerosols to clouds over the ocean, which could reflect sunlight back into space and potentially reduce global warming.

In an exploration of conflict and diplomacy, president and founder of Eurasia Group and GZERO Media Ian Bremmer joins TED's Helen Walters to unravel the ideological underpinnings, contrasting objectives and humanitarian crises defining the current situation in Gaza.

In an exclusive preview of unreleased technology, designer and inventor Jason Rugolo unveils an entirely new kind of computer you can talk to like a friend. This "audio computer" — which can augment the sounds around you, translate conversations in real time, naturally respond to your voice and more — promises to shake up how we use our devices. It's shown publicly for the first time ever on the TED stage.

The political system in the United States needs a redesign, says political reformer Andrew Yang. Exposing the flaws of a system built on poor incentives, he proposes a cost-effective overhaul inspired by primary elections already working in places like Alaska and advocates for ranked-choice voting, where voters can choose candidates in order of preference regardless of party, stemming the influence of extreme ideologies.

How much should we invest in teachers, and what should new investment actually involve? Education innovator Randy Seriguchi Jr. suggests the US should create a "G.I. Bill" for teachers, with a particular emphasis on uplifting Black male professionals. He shares a model of this idea in action through community partnerships in San Francisco, which provide aspiring teachers with graduate school tuition, subsidized housing, personalized fit assessments and more. "If we truly want to elevate this profession to inspire new, diverse talent to join us, we have to improve both the personal and professional experiences associated with teaching," says Seriguchi.

Each Sunday, TED shares an episode of another podcast we think you'll love, handpicked for you … by us. Today: in celebration of Star Wars Day, we're sharing an episode from The Redemption of Jar Jar Binks, TED's first narrative show. It explores how Jar Jar Binks became one of the most polarizing figures in cinematic history when he made his debut in Star Wars Episode 1: The Phantom Menace. It’s 1999, and sixteen years after its original release, a new Star Wars is finally coming. Fans have been camping out in front of theaters across the country just to be the first to see it. The beloved intergalactic saga is set to debut a slew of brand new characters, one of whom is a revolutionary CGI creation named Jar Jar Binks. Whispers begin to spread about big changes coming to the galaxy far, far away — and not everyone’s happy about it. Transcripts for The Redemption of Jar Jar Binks are available at go.ted.com/jarjar

When it comes to climate, what are we doing right and where should we focus our efforts next? Systems innovator Ryan Panchadsaram and strategist Anjali Grover talk with TED science curator David Biello about the latest on the world's progress toward solving the climate crisis — and why there's more reason for optimism than you might think. Using strategic goal-setting tools that have transformed countless organizations, Panchadsaram and Grover explore the urgent actions needed to steer the planet toward a sustainable future and the pivotal roles of innovation, investment and policy. "The climate story isn't yet written," Grover says.

Marrying for love is a relatively recent phenomenon for humanity, and we still don't fully understand what it means for building successful relationships, says author and psychiatrist George Blair-West. Drawing from his extensive experience working with couples, he shares four questions every couple should ask themselves before tying the knot — and highlights surprising findings on how the way marriage starts impacts if it ends.

In a scorching talk, marketing professor and podcaster Scott Galloway dissects the data showing that, by many measures, young people in the US are worse off financially than ever before. He unpacks the root causes and effects of this "great intergenerational theft," asking why we let it continue and showing how we could make it end. (Note: This talk contains mature language.)
