Thomas Woodside and Sunny Gandhi  worked on SB1047, a California bill focused on national security and public safety risks from advanced AI systems. We discussed their experiences advocating for the bill, speaking to legislators and industry experts, amending the bill in response to feedback, and reflecting on lessons learned for future AI policy efforts. Thomas Woodside is a policy analyst at the Center for AI Safety Action Fund, one of the co-sponsors of SB 1047. Before that, he was a junior fellow at the Center for Security and Emerging Technology at Georgetown, where he wrote technical explainers for policy audiences and did some grantmaking. He did his undergraduate in computer science at Yale. Sunny Gandhi is the Vice President of Political Affairs at Encode Justice, an organization advocating for safe and responsible artificial intelligence where he has experience working in AI governance at both federal and state levels. Sunny has previously held technical roles at Deloitte and NASA and has worked with the US State Department and the law firm Mayer Brown. He graduated from Indiana University this past May.
