Digital technologies are frequently considered as lacking material aspects. Today, it is evident that behind digital technologies lies a huge and complex material infrastructure in the form of fiber optic cables, servers, satellites, and screens. Postphenomenology has theorized the relations to material things as embodiment relations. Taking into account that technologies can also have hermeneutic aspects, this theory defines hermeneutic relations as those in which we read the world through technologies. The article opens with a review of some theoretical developments (...) to hermeneutic relations with a special focus on digital technologies. The article suggests that in the digital world, material hermeneutics needs to be updated as it shifts from a scientific to an everyday technological context. Now, technologies not only “give voice” to things, they also produce new meanings to informational structures and direct users to certain meanings. When it comes to digital technologies, especially those involving artificial intelligence (AI), the technology actively mediates the world. In postphenomenological terms, it possesses a technological intentionality. The postphenomenological formula should be updated to reflect this type of technological intentionality, by reversing the arrow of intentionality so that it points to the user, rather than from the user.

Neuroadaptive technology (NAT) is a closed-loop neurotechnology designed to enhance human–computer interaction. NAT works by collecting neurophysiological data, which are analysed via autonomous algorithms to create actions and adaptations at the user interface. This paper concerns how interaction with NAT can mediate self-related processing (SRP), such as self-awareness, self-knowledge, and agency. We begin with a postphenomenological analysis of the NAT closed loop to highlight the built-in selectivities of machine hermeneutics, i.e., autonomous chains of algorithms that convert data into an assessment (...) of psychological states/intentions. We argue that these algorithms produce an assessment of lived experience that is quantitative, reductive, and highly simplistic. This reductive assessment of lived experience is presented to the user via feedback at the NAT interface and subsequently mediates SRP. It is argued that congruence between system feedback and SRP determines the precise character of the alterity relation between human user and system. If feedback confirms SRP, the technology is regarded as a quasi-self. If there is a disagreement between SRP and feedback from the system, NAT is perceived to be a quasi-other. We argue that the design of the user interface shapes the precise ways in which NAT can mediate SRP. (shrink)
