Samsung wants to “copy and paste” the brain into a chip

Much is made of the brain-computer interfaces and the peculiarity, arguing that our consciousness may be connected to cyberspace, which sometimes reaches almost religious fervor. Samsung added fuel to this fire by announcing a method of “copying and pasting” the brain map of the neural connection on a computer chip.

In this way, they believe they could “create a memory chip that brings together the unique computing features of the brain – low power, easy learning, environmental adaptation and even autonomy and knowledge – that were beyond the reach of modern technology”, Samsung explains in press release.

The method is described in detail in a document published in the magazine Nature, uses an array of nanoelectrodes that effectively enters a large number of neurons and records their electrical signals. These records are then used to map the neural cabling by detailing the strength of the various neural connections. This “copy” of the neural connections of the brain can essentially be “placed” in a chip memory, such as an SSD or in a random access memory (RRAM). Each memory will be programmed so that “its conductivity represents the strength of each neural connection in the copied card,” the technology company said in a statement.

Reverse engineering of the brain

According to Samsung, this approach would be a return to the attempts at reverse engineering of the brain, which began with the advent of neuromorphic engineering in the 80s. Of course, the complexity of the human brain is incredibly difficult to imitate. While the Samsung team has laid the groundwork for their approach, we are still a long way from seeing a neuromorphic chip that will need approximately 100 trillion units of memory to provide a truly similar representation of all neurons in the brain and synaptic connections.

The new newspaper may eventually lead to more human artificial intelligence and there may also be applications for the connected area of ​​brain-computer interfaces (BCIs) that allow users to control computers with their minds. In 2019, Elon Musk made a presentation for his company Neuralink in which he explains that his BCI technology could one day help treat brain disease and that it could mitigate the existential threat of artificial intelligence – “if you can’t beat them, join them,” Musk wrote on Twitter last year on the Neuralink mission.
