A major race is underway in brain-computer interfaces (BCIs), technology that lets people with paralysis control devices and prosthetics using their minds.

Fewer than 100 people have permanent implants so far, but that number is expected to more than double within a year as companies like Neuralink, Paradromics, Synchron, and Precision Neuroscience advance clinical trials.

Apple plans to enable implants to control iPhones soon.

While the market could reach $1 billion annually by 2041, experts caution BCIs remain medical devices with serious risks, not consumer gadgets, the Wall Street Journal has reported.

Upcoming trials will be critical to proving the safety, performance, and viability of these implants.
