Brain-Computer Interfaces (BCIs): How They Work, Real-World Applications, Ethical Risks, and What’s Next
Brain-computer interfaces (BCIs) are transforming how humans interact with technology by translating neural activity into meaningful commands. Once the realm of science fiction, BCIs are now a practical tool across medicine, rehabilitation, consumer electronics, and research. Understanding the landscape helps clarify both the opportunities and the limits of this fast-evolving field. What BCIs do and […]
