Theories of extended cognition and AI-extenders offer useful theoretical tools for investigating hybrid systems, where cognitive capacities are enhanced or substituted with technological means. In the “extended” view, the integrated technologies are considered as part of their users’ cognition and agency and hence should be given a stronger ethical and legal status. This paper focuses on cognitive technologies such as smart home technologies that can maintain mental health and activities of daily living, and suggests that the extended view offers an advantageous and more ethical way to view them.
