Elon Musk's Neuralink company developed a brain-computer interface chip. Noland Erbo, a 29-year-old paralyzed from the neck down, played Chess on the computer using only his mind.
The chip was implanted in Erbo's brain in January in a robotic surgery. Erbo said live that "the surgery was very easy. I was actually released from the hospital a day later and I have no cognitive impairments" However, according to him "the technology is not perfect"
