The Ethical Significance of Brain-Computer Interfaces as Enablers of Communication

This article argues that the primary ethical significance of brain-computer interfaces (BCIs) lies not in the specific content they transmit, but in their capacity to restore communicative agency to individuals otherwise excluded from ethical engagement due to conditions such as complete locked-in syndrome. While current ethical frameworks focus largely on risks, privacy, and clinical outcomes, this analysis foregrounds the ontological dimension: BCIs safeguard and re-establish the practical conditions under which autonomy, recognition, and interpersonal accountability can be exercised. Drawing on documented clinical cases, the article applies the concept of communicative reinstatement to describe how BCIs reconfigure relationships between patients, caregivers, and the broader moral community. The argument culminates in a normative claim: societies have an ethical obligation to maintain and protect communicative capacity where feasible, treating BCIs not merely as therapeutic tools but as infrastructures of moral inclusion. This reorientation carries implications for regulation, informed consent, policy, and distributive justice.
