Mind Over Machine: The Astonishing Rise of Brain-Computer Interfaces (BCIs)
In May 2023, a wireless brain-spine interface enabled a paralyzed man to stand, walk, and climb stairs after 12 years, with effects stable for over a year. Since 2004, BCI trials have let paralyzed patients move cursors, control robotic arms, feel touch, and type by thought. Neuralink began human trials in 2023, implanting its device in five patients by mid-2025. Paradromics and UCSF also reported major milestones in 2023.
