“In the first couple of weeks after returning home, Arbaugh had members of Neuralink’s team in his living room and kitchen to test the device. In research settings, brain implant patients usually need to rest after two to four hours because of mental and physical strain, but Arbaugh would go for up to 10 hours. The device also outperformed its predecessors. From Day 1, he began breaking speed records on the typical battery of tests used to benchmark the performance of brain-computer interface implants.

The world began to reopen for Arbaugh. He could play games like Sid Meier’s Civilization and chess with relative ease. He could hop between websites and audiobooks on his computer. And he could do all of this while lying in bed, which was far more comfortable and less spasm-inducing than sitting in his wheelchair and trying to get his mouth stick aligned just so with his iPad.

In the early days, Arbaugh had to learn how to tune Neuralink’s software to his brain patterns and get the gist of turning thoughts into action. As the weeks went by, the process became second nature. Arbaugh could carry on a conversation with someone while playing chess at the same time. It seemed like he’d developed a superpower.”
