    Elon Musk has expressed his company – Neuralink is close to announcing the first brain-machine interface (接口) to connect humans and computers. Musk told followers in Twitter the technology would be “coming soon” – though he failed to provide details.

Neuralink was set up in 2016 with the ambitious goal of developing hardware to strengthen the human brain. However, little about how this will work has been made public. Neuralink describes the interface as an extremely high-speed connection between the human brain and computers.

Musk has frequently claimed the rapid rise of artificial intelligence poses an existential risk to humanity. Such an interface, he says, is essential if humans are to compete with such technology in the future. At a technology conference in 2016, Mr Musk said humans risked being treated like house pets by AI machines if a brain-computer interface was not built. Last year on the Joe Rogan Experience podcast, Musk said Neuralink’s technology would allow humans to “effectively combine with AI”.

A paper published in Nature Nanotechnology in 2015 described a concept for this connection, explaining how a flexible circuit (回路) could be injected into a living brain. “We’re trying to lessen the distinction between electronic circuits and neural circuits,” said Harvard researcher Charles Lieber, who co-authored the study. Despite the technology’s potential to increase the human brain, experts have warned that brain-computer interfaces risk being controlled by vicious (恶意的) artificial intelligence.

Such an action could lead to AI controlling the thoughts, decisions and emotions of a person using a brain-computer link. “Technological developments mean that we are on a path to a world in which it will be possible to discover people’s mental processes and directly operate the brain mechanisms underlying their intentions, emotions and decision,” stated a Nature comment piece written by 27 scientists and machine intelligence engineers. “The possible medical and social benefits in it are vast. But we must guide their development in a way that respects, protects and enables what is best in humanity.”
