Neuralink, Elon Musk's brain-computer interface firm, published a video showing the first human patient using the implant to operate a mouse cursor and play chess.
Noland Arbaugh, 29, was paralyzed below the shoulders eight years ago in a diving accident.
The Neuralink implant lets Arbaugh “just stare somewhere on the screen” and move the pointer, like the Force from Star Wars.
Musk, who founded Neuralink in 2016, shared Arbaugh's video, calling it "telepathy."
The Neuralink implant allowed Arbaugh to play Civilization VI for eight hours straight, but he had to wait for it to charge.
After receiving FDA approval to perform in-human clinical trials last year, Neuralink revealed that it was recruiting test subjects for a six-year trial.
After Musk said in January that the first trial participant was “recovering well” from the brain implant, Neuralink released the first video of a human using it.
It comes less than three years after the company released a video of a chimpanzee using the technology to play Pong.
