Neuralink's N1 brain implant has enabled ALS patient Nick Wray to control a robotic arm via thoughts alone, as part of the FDA-approved CONVOY study aimed at restoring independence for the severely paralyzed. The coin-sized device, with 1,000 electrodes on ultra-fine threads, translates neural signals into Bluetooth commands for tasks like picking up cups, microwaving food, and even maneuvering a wheelchair. In dexterity tests, Wray set records—moving 39 cylinders in 5 minutes and flipping pegs—
