Artificial Intelligence Decodes Thoughts Into Language Using Brain Scans

A new AI system can translate a person's thoughts into words using functional magnetic resonance imaging.
The system requires extensive individual training but could help patients who have lost the ability to speak communicate again.
The technology raises ethical concerns about privacy and mental surveillance that policymakers need to address.
The system captures the gist and meaning of thoughts but currently requires hours of fMRI scanning and is not practical outside the lab.
The researchers have taken steps to protect participants' privacy but acknowledge the potential for misuse and the need for oversight.
