Brain-Computer Interfaces: How far can we, and how far should we go?

Brain-computer interfaces (BCIs) are moving from research labs into clinical applications, with meaningful impact. As breakthroughs accelerate across invasive, minimally invasive, and noninvasive technologies, fundamental scientific, ethical, and societal questions arise: Who owns neural data? How do we protect privacy when thoughts can be decoded? And where is the line between therapy, enhancement, and autonomy? Let’s explores where the field is heading, what safeguards are needed, and how these technologies may reshape our future.
