Can Elon Musk's brain technology from Neuralink revolutionize the world?

Elon Musk's Neuralink division has made a bold claim, stating that it has successfully implanted its first wireless brain chip into a human. Musk believes that this technology could potentially save the human race in the long term. While the concept of implanting electrodes into brain tissue is not new, the development of implantable technology has taken time to mature. Various companies and university departments, including Neuralink, are working on refining and commercializing brain-computer interface (BCI) technology. BCIs can detect electrical signals generated by neurons in the brain, allowing individuals to control computers or devices with their thoughts. Neuralink's device, about the size of a coin, is implanted in the skull and can read neuron activity, transmitting wireless signals to a receiver. The company has conducted trials on animals and has received approval for human trials in 2023. However, other companies, such as Synchron, have already implanted similar devices into patients. While some people with spinal injuries are skeptical about the progress in implantable technology, Musk sees solving brain and spinal injuries as just the first step. His long-term goal is to achieve human/AI symbiosis, which he considers of species-level importance. The challenge lies in developing a system that can accurately interpret brain signals and allow seamless communication between humans and electronic devices. Though there are skeptics who question the practicality of invasive brain surgery for consumer benefits, experts believe that the initial mass market applications may involve stimulating the brain to address various conditions. The widespread use of Neuralink's technology is considered to be decades away. Musk sees this technology as a means to protect humanity from the risks associated with artificial intelligence, describing it as an "existential threat" that can be mitigated by combining human and computer brains.
