Does AI pose a threat to democracy? Law professor Lawrence Lessig dissects how this emerging technology could influence democratic institutions, warning that we’ve already passed a point (before superintelligence or AGI) that deserves a lot more attention. After the talk, Sherrell reflects on the importance of media literacy and the need to remain vigilant and engaged to defend our democracy.

We're fast approaching a world where widespread, hyper-realistic deepfakes lead us to dismiss reality, says technologist and human rights advocate Sam Gregory. What happens to democracy when we can't trust what we see? Learn three key steps to protecting our ability to distinguish human from synthetic — and why fortifying our perception of truth is crucial to our AI-infused future.

"Democracy is more fun and inviting when you take it into your own hands," says creator and activist Sofia Ongele. Sharing how she's using coding and social media to defend democracy, Ongele invites us to identify our own creative superpowers — whether it's community organizing, making music or telling stories — and use them to cause a ruckus and bring movements to life.

No one truly understands AI, not even experts, says Helen Toner, an AI policy researcher and former board member of OpenAI. But that doesn't mean we can't govern it. She shows how we can make smart policies to regulate this technology even as we struggle to predict where it's headed — and why the right actions, right now, can shape the future we want. After the talk, Sherrell expands on what’s needed to ensure that AI aligns with the best interests of humanity, without stifling innovation.

We don't have to sacrifice our freedom for the sake of technological progress, says social technologist Divya Siddarth. She shares how a group of people helped retrain one of the world's most powerful AI models on a constitution they wrote — and offers a vision of technology that aligns with the principles of democracy, rather than conflicting with them.

When James G. Robinson's son Nadav was born with a rare heart defect, he feared the worst. What he didn't anticipate were the moments of unexpected wonder. In this profound talk, Robinson traces five years of impossible medical odds, a genetic discovery so strange it felt like fate ... and how grateful he is to have experienced it all.

What if GLP-1s like Ozempic could do more than just tip the scales? Physician Dhruv Khullar traces the winding path of the "moderation molecule" — from a discovery in Gila monster saliva to a potential diabetes medication and addiction treatment — and how they could quiet the relentless noise of craving. The most surprising effects of GLP-1s may not be in the gut, but in the brain.

Genome researcher Michael Snyder believes health wearables, such as smart watches and glucose monitors, can transform medicine, shifting from reactive to predictive. (In fact, he's such a big fan of these devices that he wears eight of them every single day.) From spotting an illness days before symptoms appear to helping prevent the onset of diabetes, learn why the future of health care may be on your wrist.
