On the Fundamental Limitations of AI Moral Advisors

Abstract In “Against Personalized AI Moral Advisors” (Philosophy & Technology, 38(2):45, 2025), Muriel Leuenberger has argued that the personal nature of practical deliberation, which I stressed in my “Can AI Rely on the Systematicity of Truth? The Challenge of Modelling Normative Domains” (Philosophy & Technology, 38(34):1 -27, 2025a), counterintuitively militates against the development of personalized AI moral advisors and in favour of generalist AI moral advisors. Here, I take up and develop this line of thought, drawing out how the asystematicity of normative domains reveals the fundamental limitations of both personalized and generalist AI moral advisors.
