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.

Musk has strong opinions about the risk of artificial intelligence, saying it could turn evil and pose a threat to humanity. One time, he went so far as to compare AI to "summoning the demon."

"I don't love the idea of being a house cat, but what's the solution? I think one of the solutions that seems maybe the best is to add an AI layer," Musk said in June. "A third, digital layer that could work well and symbiotically."

In 2015, Musk and Y Combinator's Sam Altman founded OpenAI, a nonprofit with the mission to advance "digital intelligence in the way that is most likely to benefit humanity as a whole."

The neural lace concept, which Musk last said he was "making progress" on in August, seems to fit with OpenAI's mission. But we'll have to wait for more details.
