'It's only going to get better': Musk moving on to second person to test brain tech

Neuralink, led by Elon Musk, is advancing brain-computer interface technology and has moved to its second patient. The first patient, Noland Arbaugh, paralyzed from the shoulders down, successfully controlled a computer cursor with his brain. Neuralink resolved initial issues and aims to implant deeper threads for better signal detection. Musk envisions future enhancements providing superhuman abilities.
