Elon Musk may be gearing up for his strangest announcement yet on artificial intelligence

Elon Musk hasn't given up on his vision to add a digital layer of intelligence to our brain. The Tesla and SpaceX CEO teased that he may have an announcement about "neural lace," a concept he first brought up at Vox Media's Code Conference in June, coming next month on Twitter Wednesday morning. Musk first described neural lace as a brain-computer system that would link human brains with a computer interface. It would allow humans to achieve "symbiosis with machines" so they could communicate directly with computers without going through a physical interface. Musk has said a neural lace will help prevent people from becoming "house cats" to artificial intelligence.
