The first human to have a Neuralink computer chip surgically implanted in his brain demonstrated how he uses his thoughts to move a computer cursor around a screen to play online chess and toggle on and off a music stream.

Noland Arbaugh, a 29-year-old man who is paralyzed from the shoulders down due to a diving accident eight years ago, joined a live stream alongside a Neuralink engineer on X to show the public how the brain-computer interface tech works.
