Elon Musk believes he knows how to connect human brains with computer interfaces via artificial intelligence.

The billionaire said his start-up Neuralink would be ready to demonstrate the brain-computer interface technology later this year.

While Musk was keeping his cards close to his chest, the tech icon promised the latest iteration of the product would be "awesome".

The concept would see minuscule, flexible electrode "threads" implanted into the human brain by a neurosurgical robot, which would then record electrical signals.

Musk believes the product would create a scalable high-bandwidth brain-machine interface that allows humans brains to connect to an external device.

The billionaire said he believes the biggest advantage would be helping humans overcome disabilities and injuries.

"It will ultimately be used to make up for entire lost sections of the brain due to stroke/accident/congenital. Don't want to get too excited, but the potential is truly transformational for restoring brain and motor functions. There is no other way to do it imo (in my opinion)," he explained.

Musk claims the technology has already allowed a monkey to control a computer with its brain in tests, with hopes to move to humans when safe.

"First, we need to make it super safe & easy to use, then determine greatest utility vs risk. From initially working to volume production & implantation is a long road," he said.
