Newcastle University neuroscientist Professor Andrew Jackson told Business Insider that getting monkeys to play video games with brain control interfaces was first done in 2002, but Neuralink’s work is “definitely new and innovative” because it was done without cables sticking out of the monkey’s brain. The Imperial College London’s Dr. Rylie Green told the site it was important the monkey seemed well, and not at all surgically mangled or anything like that.

“The best thing I can see from that video is that the macaque is freely moving,” Green told Business Insider. “There’s also no visible package connected to it. I would say that is definitely progress—not super innovative but a nice positive step forward.”
