Mind meld: How Elon Musk wants to connect brains to computers

Tesla Motors CEO Elon Musk unveils the company's newest products in Hawthorne, Calif. Elon Musk, already the CEO of two companies, appears ready to embark on his next project: a neural interface melding the human brain with computer technology. In an interview with the website Wait But Why, the head of Tesla and SpaceX says his latest endeavor -- Neuralink -- is four years away from introducing its first product to market. The initial version of the Neuralink device would focus on people with severe brain injuries. "The first use of the technology will be to repair brain injuries as a result of stroke or cutting out a cancer lesion, where somebody's fundamentally lost a certain cognitive element," said Musk. "It could help with people who are quadriplegics or paraplegics by providing a neural shunt from the motor cortex down to where the muscles are activated."
