2years of independent speech
Because of AI, a man with ALS has spoken with his family and kept working from home for two years through a brain implant, at up to 99% word accuracy.
UC Davis's intracortical BCI uses deep-learning brain-to-text and cursor decoders with continuous fine-tuning; Nature Medicine (June 2026) documented Casey Harrell's near-daily unassisted use at home for roughly two years.
