My PhD dissertation explores the political implications of artificial intelligence across three critical areas: job automation, public opinion on the use of AI in public policy, and the role of chatbots as citizen representatives in political participation. The first chapter examines how the threat of job automation influences economic and social welfare policy preferences, analyzing the impact on labor markets and the resulting shifts in public demand for employment policies and social protection measures. The second chapter delves into public opinion regarding AI in policymaking, assessing factors that shape trust and acceptance of AI-driven decisions and highlighting the need for the appropriate measurements of perceptions in implementing democratic AI governance. The third chapter investigates the use of chatbots as agents participating on behalf of citizens in virtual councils, exploring their potential to enhance political decision-making by providing diverse and inclusive digital representation and discussing the technical, ethical, and legal challenges associated with their deployment in local governance.
