Billionaire Elon Musk is known for his futuristic ideas. So it didn't come as a surprise when on Monday at the World Government Summit in Dubai, he predicted that over time we will see a "closer merger of biological intelligence and digital intelligence." He added, via a CNBC report: "It's mostly about the bandwidth, the speed of the connection between your brain and the digital version of yourself, particularly output." Musk explained what he meant by saying that computers can communicate at "a trillion bits per second", while humans, whose main communication method is typing with their fingers via a mobile device, can do about 10 bits per second. In an age when AI threatens to become widespread, humans would be useless, so there's a need to merge with machines, according to Musk. "Some high bandwidth interface to the brain will be something that helps achieve a symbiosis between human and machine intelligence and maybe solves the control problem and the usefulness problem," Musk explained.
