Tesla founder and Chief Executive Elon Musk said his latest company Neuralink is working to link the human brain with a machine interface by creating micron-sized devices.

Neuralink is aiming to bring to the market a product that helps with certain severe brain injuries due to stroke, cancer lesions, and so on, in about four years, Musk said in an interview with website Wait But Why.

"If I were to communicate a concept to you, you would essentially engage in consensual telepathy," Musk said in the interview published on Thursday. The interview was part of a nearly 40,000-word article that explains in detail the science of the human brain and how Neuralink will aim to connect to it.

Artificial intelligence and machine learning will create computers so sophisticated and godlike that humans will need to implant "neural laces" in their brains to keep up, Musk said in a tech conference last year.

"There are a bunch of concepts in your head that then your brain has to try to compress into this incredibly low data rate called speech or typing," Musk said in the latest interview.
