The ethical challenges posed by artificial intelligence can be examined from the perspective of the innovation economy. This is characterized by interactions between companies capable of investing considerable sums, start-ups that invent original solutions, professionals (medical practitioners, care teams) who use them, and patients who benefit from them. These interactions are overturning the way medical decision-making used to be based on the scientific authority of medical practitioners. How can we give stability to the varied power games that characterize AI-assisted healthcare? One of the avenues to be explored is that, in the absence of a new Leviathan (Hobbes, 1651) guaranteeing a single public authority considered all-powerful for knowledge, a remediation path is provided by participative technology codesign practices, including workshops to explore ethical issues in greater depth.
