Ethics of Brain-Computer Interfaces

Analyze the promise and risks of brain-computer interfaces for people with severe paralysis or neurodegenerative disease. Explain how such systems can improve communication and autonomy, then examine the ethical, clinical, and social questions they raise: consent, safety, privacy of neural data, long-term maintenance, inequality of access, and how society should define success for these devices. Conclude with practical guidelines for patients, clinicians, and policymakers evaluating whether the benefits justify the tradeoffs.
