Buckle up: It’s time for TED! In a classically eclectic opening session, seven speakers and a performer explore the big issues of the day — from the rise of techno-authoritarianism and the existential threat of superhuman AI to the rebirth of Notre-Dame de Paris and signs of progress from around the world. Also, the humanoid helper NEO opens the show … because what would TED be without a surprise cameo from a robot?
Here are some key takeaways from day 1:

Politics is technology now. In the searing opening talk of TED2025, investigative journalist Carole Cadwalladr explores how a fast-moving technological coup is threatening democracy around the world. The alignment of corporate power, massive data collection and emerging autocratic regimes has created what she calls “the broligarchy” — an unprecedentedly powerful class of tech bro oligarchs who are complicit in enabling authoritarian control on a scale never seen before. She says it’s time for people to digitally disobey: don’t accept cookies, don’t use your real name, use encrypted messaging services like Signal and support those defending data rights and freedom of expression. “Privacy is power, and we have more of it than we think,” Cadwalladr says.

With AI, we are playing with fire. Computer scientist Yoshua Bengio is at the forefront of deep learning research and AI development — and he’s also a leading voice in the effort to curb the risks of superhuman AI. He explains why, as AI develops tendencies to deceive, cheat and self-preserve, the world should treat the risk of extinction from AI as a global priority alongside pandemics and nuclear war. He also presents a technical solution to the problem: “scientist AI,” an intrinsically safe and trustworthy version of the technology developed as a global public good and used for human flourishing.

An artist-powered revolution is coming. Streaming platforms, corporate gatekeepers and now AI have systematically eroded the power of artists, as musicians, writers, designers and other creative people struggle to earn a living. The solution? Writer and entrepreneur Yancey Stickler suggests that a radical new legal structure — the “Artist Corporation” — could give creators real economic and organizational power by pooling resources, sharing ownership and attracting investment on their own terms. Artists don’t need pity or prestige prices, Strickler says. They need a seat at the table.

One of history’s most iconic cathedrals, reborn from the ashes. Led by chief architect Philippe Villeneuve, the revival of Notre-Dame de Paris following a massive fire in 2019 is more than a rebuild — it’s a blueprint for future restoration efforts. Drawing on time-honored techniques, Villeneuve shares how a team of craftspeople and experts came together to bring new life to this Gothic masterpiece — a bold act fueled by passion, precision and purpose.

Hope still exists, if you know where to look. From a groundbreaking malaria vaccine saving children to a sharp drop in Amazon deforestation, journalist Angus Hervey puts a spotlight on overlooked breakthroughs in a world teetering between collapse and progress. He reveals how humanity is persistently making strides toward a better future — even if these stories are regularly missing from the headlines.
