The race to link our brains with AI: Inside Elon Musk and Sam Altman's battle to be first to connect mind and machine

The tussles between billionaires have seen vast fortunes splashed on everything from rocket ships to social media empires. But now, two titans of big tech are taking their fight to a frontier: The race to link our brains with AI. Tesla and xAI CEO Elon Musk and Sam Altman of OpenAI, the company behind ChatGPT, are vying to be the first to connect mind and machine. The former allies are now both backing rival companies trying to build brain-computer-interface (BCI) chips and put them inside humans. These devices allow people to directly control computers with their thoughts by reading the electrical signals produced in the brain. As outspoken champions of the technology, both Mr Musk and Mr Altman claim that BCIs will one day allow humanity to merge with artificial intelligence.
