“In March, Elon Musk’s brain-computer interface company Neuralink introduced its first human trial participant, a quadriplegic who showed the world how he could control a computer cursor with just his thoughts. 

On Wednesday, the company said its second patient is playing videogames, using design software and so far has avoided the issue that nearly derailed the first patient’s implant.

Neuralink’s fully implantable, wireless device—if it proves safe during clinical trials—would be a major upgrade on older technology, returning function to thousands of disabled individuals who have lost it.”
