Inside the science behind Elon Musk's crazy plan to put chips in people's brains and create human-AI hybrids

Tesla CEO Elon Musk has an unusual passion project: a neural tech company called Neuralink. Musk cofounded Neuralink in 2016, and the company remained relatively under the radar until 2017 when the Wall Street Journal broke the news that he had established the company to "merge computers with human brains." Developing brain chips is a curious side hustle for a man who is simultaneously running Tesla, his space exploration company SpaceX, and The Boring Company, which Musk hopes will dig underground transit systems for cities. The entrepreneur has frequently been vocal about his worries that AI could one day come to overshadow the human race. He's founded a general-purpose research organization called OpenAI but Neuralink has a much more tangible, futuristic goal of making AI-enabled devices capable of interacting with people's brains.
