Elon Musk's $27m plan to plug the brain into a computer

Elon Musk's controversial startup to crate a'Matrix' interface to plug the human brain directly into a computer has raised over $27m, it has been revealed. Called Neuralink, SEC filings have revealed the scale of the firm for the first time. It has raised the $26.96 million of a technically still-open funding round that could grow to $100 million - although Musk took to Twitter to say the firm is no longer raising cash. Elon Musk's latest company Neuralink is working to link the human brain with a machine interface by creating micron-sized devices. Neuralink was registered in California as a'medical research' company last July, and he plans on funding the company mostly by himself.
