Meta's brain-scanning system reads sentences non-invasively, code open source

The scoop

How close are we to reading people's thoughts without surgery? Meta's Brain2Qwerty v2 decodes sentences directly from non-invasive brain scans with 61% word accuracy, approaching surgical implant performance levels. The system uses AI to translate magnetoencephalography recordings into text, potentially helping people with communication disorders, though readers note practical challenges around device cost and size, plus concerns about privacy implications.
