Neuralink, the Elon Musk-led startup that the multi-entrepreneur founded in 2017, is working on technology that's based around'threads' which it says can be implanted in human brains with much less potential impact to the surrounding brain tissue vs. what's currently used for today's brain-computer interfaces. "Most people don't realize, we can solve that with a chip," Musk said to kick off Neuralink's event, talking about some of the brain disorders and issues the company hopes to solve. Musk also said that long-term Neuralink really is about figuring out a way to "achieve a sort of symbiosis with artificial intelligence." "This is not a mandatory thing," he added. "This is something you can choose to have if you want."
