12.4 Challenges and opportunities in BCI development

Brain-Computer Interfaces (BCIs) face technical, ethical, and societal hurdles. From signal processing to privacy concerns, these challenges require innovative solutions. Interdisciplinary collaboration is key, bringing together experts from neuroscience, engineering, ethics, and more to tackle complex BCI issues.

BCIs are set to revolutionize healthcare, work, and communication. As they reshape our economy and society, careful consideration of their impact is crucial. Policymakers and researchers must work together to ensure responsible BCI development, balancing innovation with ethical concerns and societal needs.
