Human Dignity and the Future of Personhood in AI-Integrated Brain-Computer Interfaces.

Résumé

The advancements in neurotechnology, especially brain-computer interface (BCI) technologies, signal an ethically challenging phase in the relationship between human beings and artificial intelligence. The boundaries between ‘purely biological cognition’ and machine intelligence continue to blur. The current objectives of tech giants such as Neuralink are primarily therapeutic, focusing on restoring communication and neurological functions. However, future developments may enable direct integration between the human brain and AI-integrated BCIs such as generative artificial intelligence (GenAI) systems through implantable brain chips or other devices. This will create new possibilities for cognitive enhancement, expanded memory, accelerated learning, and augmented decision-making. This conceptual paper critically examines the ethical implications of AI-integrated brain enhancement from the perspective of human personhood and dignity. Although the ethical implications of brain-computer interfaces have received growing scholarly attention, much of the existing literature has concentrated on issues such as safety, privacy, cybersecurity, regulation, and informed consent. Comparatively less philosophical attention has been devoted to examining AI-integrated cognitive enhancement through the combined lenses of personhood, human dignity, and relational understandings of the human person. The paper argues that the shift from therapeutic neurotechnology to human enhancement raises fundamental questions about the nature of human agency, autonomy, identity, and responsibility in an age where cognitive processes may increasingly involve technological mediation. It is crucial to consider whether AI-enhanced cognition represents an authentic extension of human capacities or a transformation that risks undermining essential dimensions of human personhood. Will AI-integrated brain enhancement support the conventional understanding of human personhood, or will it transform the very meaning of being human? Drawing on existing literature in technoethics, neurotechnology, and philosophy of technology, the study argues that the ethical evaluation of BCI technologies should not be determined solely by technological capability or efficiency, but by their capacity to preserve human dignity, meaningful autonomy, and responsible self-determination. As humanity moves towards deeper integration with artificial intelligence, the central ethical challenge lies beyond whether humans can enhance themselves through neural technologies. It is primarily centred on interrogating whether such enhancement can be pursued in ways that safeguard the distinctive value, freedom, and dignity of the human person. By integrating the extended mind hypothesis, the transformation hypothesis, human dignity, and Ubuntu, the paper proposes a normative framework for evaluating future AI-integrated neurotechnologies.
