‘Care’ and different forms of conceptualising, valuing and ‘doing care’ has always been the focus of my research. As a Science and Technology Studies (STS) researcher and philosopher of technology, I do qualitative studies on care in the crossroads of new emerging technologies and changing medical contexts. Since every technology comes with its own promises (and perils), I use case studies (a specific emerging technology and in-depth interviewing with relevant stakeholders and intended users) to show that technologies are not simply utopic or dystopic ‘things’ but can enable reflections and discussions about changes in our lifeworlds. These are typically much more nuanced and spread over a broad spectrum between desirable and undesirable. I critically explore value changes and practical responses that co-emerge with new technologies. Such case study explorations help to envision and map the different value-trade offs (e.g. safety in relation to privacy/freedom; desirability for whom? In what context? Under which circumstances and which kinds of costs?) that can become possible. Mapping different forms of technology-care relationships in situated practices can support decision making processes that aim to assess the desirability and practical possibilities of emerging technologies such as current technology assessment approaches and anticipatory governance.
