José Villalobos Ruiz, based at the Institute for Law & AI, proposes an international treaty on the prohibition of misaligned AI. Ruiz will focus on what the legal side of an ideal treaty on the prohibition of misaligned AGI might look like, addressing the question in three steps. The first step will be a comparative analysis of existing legal instruments that prohibit technologies or activities that may pose an existential risk, from nuclear weapons to greenhouse gas emissions beyond a certain cap; the second step will be to identify how existing legal frameworks may fail to address risks posed by AGI; the third will be to recommend ways in which those weaknesses could be tackled in a treaty that prohibits (misaligned) AGI.
