Artificial Intelligence, Ontology, and Existential Risks

Some future forms of AI may kill us all, or at least irremediably maim our hopes to enjoy the benefits of great technological advances in the future – or so some philosophers working on existential risk have recently claimed. But what does ‘our’ stand for in this context – and why could the extension of that term not include, say, superintelligent AIs as well? This paper explores several foundational issues in the recent debates on existential risks related to AI, with a particular focus on the conceptual connections between ontological theories of our nature – answers to the question, ‘What am I?’ — and recent formulations of the notion of an existential risk.
