Brad G. Smith, an ALS patient, has regained the ability to communicate using a Neuralink brain-computer interface (BCI). The implant, which connects to his motor cortex, allows Smith to control a cursor on his MacBook Pro by interpreting signals from 1024 electrodes embedded in his brain. This system represents a significant advancement over previous technologies, as it enables natural interaction with the world, including engaging in games like Mario Kart and using a virtual keyboard. Smith previously relied on eye-tracking systems, which were limited by environmental factors, but the Neuralink device provides more consistent performance. The device also includes features like a “parking spot” for the cursor, allowing for passive engagement with media. Neuralink has received a “breakthrough” designation from the FDA, opening the door for potential use in treating speech impairments caused by ALS and other neurological conditions. Ethical considerations around brain-computer interfaces are now under scrutiny, as they raise questions about data privacy and the future of human interaction.
