Although not a universally held goal, maintaining human-centric artiﬁcial intelligence is necessary for society’s long-term stability. Fortunately, the legal and technological problems of maintaining control are actually fairly well understood and amenable to engineering. The real problem is establishing the social and political will for assigning and maintaining accountability for artefacts when these artefacts are generated or used. In this chapter we review the necessity and tractability of maintaining human control, and the mechanisms by which this can be achieved. What makes the problem both most interesting and most threatening is that achievingconsensusaroundsuchanapproachrequiresatleastsomemeasureofagreement on broad existential concerns.
