Soon we will be sharing a large part of our social lives with various kinds of artificial agents. However, many notions in philosophy describing socio-cognitive abilities are rather restrictive. To describe human-machine interactions which cannot be reduced to tool-use, we lack appropriate notions. In this talk, I will demonstrate how one can develop a notion of joint action that is applicable to human-machine interactions. Thereby, I question whether our conception of sociality should be limited to living beings. In the second part of my talk, I will argue that even if one would still interpret human-machine interactions in an instrumental way, there are reasons why we should consider social norms regulating our interactions with artificial agents.
