AI and brain-computer interface allow speechless ALS patient to work a full-time job

A brain-computer interface (BCI) system developed by the University of California, Davis, and the BrainGate coalition has enabled Casey Harrell, an ALS patient, to communicate and work full-time since 2023. The system translates brain activity into speech with high accuracy, allowing Harrell to engage in daily conversations and professional tasks despite paralysis.
