Billionaire Elon Musk said in a tweet on Sunday pushed back by a month the date for Neuralink's "show & tell" event to Nov. 30 and did not provide further information. The chief executive of electric car maker Tesla Inc and rocket developer SpaceX said in August that the event would be held on Oct. 31. Co-founded by Musk in 2016, San Francisco-based Neuralink aims to implant wireless brain computer chips to help cure neurological conditions like Alzheimer's, dementia and spinal cord injuries and fuse humankind with artificial intelligence.
