Dr. Tom Oxley visibly stiffens at the prospect of using brain-computer interface technology for something as gauche as augmenting able-bodied humans. “We're not building a BCI to control Spotify or to watch Netflix,” the CEO of medical device startup Synchron tersely told Engadget via videocall last week.

“There's all this hype and excitement about BCI, about where it might go,” Oxley continued. “But the reality is, what's it gonna do for patients? We describe this problem for patients, not around wanting to super-augment their brain or body, but wanting to restore the fundamental agency and autonomy that [able-bodied people] take for granted.”
