The Future of Computer-Brain Interfaces
Looking ahead
What may improve
Future BCIs may become smaller, safer, more accurate, and easier to use. Better sensors, better algorithms, and better understanding of the brain could all improve performance.
What will still matter
Even as technology improves, the most important issues will remain usefulness, safety, privacy, and fairness. A system should help people without creating new problems.
A realistic view
BCIs are promising, but they are not magic. Progress will likely be gradual, with many small improvements rather than one sudden breakthrough.
