This article explores the intersection of science fiction, philosophy, and ethics in the context of emerging technologies, with a specific focus on Brain–Machine Interfaces (BMIs). It asks how the development and potential normalization of BMIs may transform our understanding of autonomy, agency, identity, and justice, and whether speculative fiction can illuminate the ethical and socio-political implications of these transformations. Science fiction, with its imaginative exploration of alternative futures, offers a unique platform for anticipating the ethical challenges posed by technological advancement. Speculative narratives invite critical reflection on issues such as autonomy, identity manipulation, justice, and the concentration of power in the hands of corporations and governments. Through an examination of works such as John Scalzi’s Lock In, Mary Robinette Kowal’s The Spare Man, and S. B. Divya’s Machinehood, this article highlights emerging ethical dilemmas and the far-reaching societal changes that the widespread adoption of BMIs could give rise to. Ultimately, these narratives provide a philosophical lens through which to examine the relationship between technology and human values, offering ethical insights that may help anticipate future challenges.
