AI systems are becoming deeply embedded in every facet of our lives: from the way we listen to music, to the manner we are hired or assigned a credit card limit. Despite their wide acceptance, these systems are black boxes, of which the consequences, once they start interacting with the sociotechnical system, are difficult to anticipate and address. Design methodology is currently unprepared to deal with this issue. Existing methods are optimised for the design of non-transient tangible artefacts rather than for things that keep changing as they are used more. Therefore, we need new methodologies to address this challenge.
