Prof. Kevin Esterling Delivers UC Open Summit 2026 Closing Keynote on AI and Democracy

Professor Kevin Esterling delivered the closing keynote at the UC Open Summit 2026, held at the University of California, Berkeley on April 23, 2026.
In his talk, he examined how emerging artificial intelligence systems are reshaping public discourse in contemporary democracies. Drawing on theories of the public sphere, he highlighted how communication technologies mediate the formation of public opinion and democratic legitimacy.
The keynote explored the role of both open-source and proprietary AI systems in this process. While open-source AI is often associated with transparency and collaboration, and proprietary systems with restricted access, Professor Esterling emphasized that their effects on democratic discourse are more complex than this distinction suggests.
He outlined two key insights from this framework. First, even closed-source AI systems can contribute positively to public discourse when integrated responsibly into platforms designed to support large-scale deliberation. Second, open-source AI systems do not automatically produce better democratic outcomes, underscoring the importance of how these tools are designed and deployed.
The talk contributed to ongoing conversations about the future of artificial intelligence, governance, and democratic communication.
