## Recent evidence

- [confirms] Meta's Brain2Qwerty Decodes Typed Text From Non-Invasive Brain Signals (2026-07-07): Meta's Brain2Qwerty decodes typed text from non-invasive brain signals, trading implant fidelity for skipping surgery entirely, per the tech report. A named lab demonstrating text decoding without implants directly advances the accessibility-over-fidelity neurotech thesis.
- [confirms] Meta's Brain2Qwerty v2 Decodes Typed Sentences From Brain Scans at 61% Accuracy (2026-07-06): Meta's Brain2Qwerty v2, a non-invasive magnetoencephalography pipeline, decodes typed sentences from brain scans at 61% accuracy, approaching surgical decoders though still too error-prone for daily use.
