Elon Musk has unveiled a pig called Gertrude with a coin-sized computer chip in her brain to demonstrate his ambitious plans to create a working brain-to-machine interface.

Axar.az informs that, the billionaire entrepreneur said on a webcast that, "It's kind of like a Fitbit in your skull with tiny wires."

His start-up Neuralink applied to launch human trials last year.

The interface could allow people with neurological conditions to control phones or computers with their mind.

Mr Musk argues such chips could eventually be used to help cure conditions such as dementia, Parkinson's disease and spinal cord injuries.

But the long-term ambition is to usher in an age of what Mr Musk calls "superhuman cognition", in part to combat artificial intelligence so powerful he says it could destroy the human race.
