This notion formed the basis for the Global Future 2045 International Congress, a futuristic conference held in New York, last week.
The conference, which is the brainchild of Russian multimillionaire Dmitry Itskov, featured Ray Kurzweil - an inventor, futurist and now director of engineering at Google - who predicted that by 2045, technology will have surpassed human brainpower to create a kind of superintelligence - an event known as the singularity.
Other scientists have said that robots will overtake humans by 2100, 'LiveScience' reported.
By 2045, "based on conservative estimates of the amount of computation you need to functionally simulate a human brain, we'll be able to expand the scope of our intelligence a billion-fold," Kurzweil said.
Substantial achievements have already been made in the field of brain-computer interfaces, or BCIs (also called brain-machine interfaces).
Jose Carmena and Michel Maharbiz, electrical engineers at the University of California, Berkeley, are working to develop state-of-the-art motor BCIs.
These devices consist of pill-size electrode arrays that record neural signals from the brain's motor areas, which are then decoded by a computer and used to control a computer cursor or prosthetic limb (such as a robotic arm).
The device records the electrical activity that encodes a simple short-term memory (such as pushing a button) and converts it to a digital signal. That signal is passed into a computer where it is mathematically transformed and then fed back into the brain, where it gets sealed in as a long-term memory.
Martine Rothblatt - a lawyer, author and entrepreneur, and CEO of biotech company United Therapeutics Corp introduced the concept of "mindclones" - digital versions of humans that can live forever - in the conference.
