Meta has unveiled Brain2Qwerty v2, a noninvasive AI-based brain-computer interface that converts brain activity into text without brain surgery. The system uses helmet-shaped magnetoencephalography equipment and an end-to-end model to reconstruct intended sentences, and it fine-tunes a large language model for neural data. Meta said average word accuracy reached 61 percent. Nine volunteers took part, and results and training code were released alongside a paper in Nature Neuroscience.

As brain-computer interfaces, AI smart glasses and robotic prosthetic arms rapidly become real, some elements of the future imagined by cyberpunk are emerging in industry and society, an assessment said. The most accurate prediction, it added, was not flashy body modification but the power structure of major technology companies dominating digital space. Commentators also pointed to the internet shifting toward closed ecosystems and raised concerns about dependence on AI coding tools.
