In view of the fact that I always see people who have opinions on the "brain-computer interface technology" in the book, I don't bother to explain anything, so I go straight to the dry goods. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The following is the result of real-world research and has nothing to do with fiction:

A brain-computer-interface (BCI) is a direct connection between the human or animal brain (or the culture of brain cells) and an external device.

Research into brain-computer interfaces has been going on for more than 40 years. Since the mid-90s of the 20th century, there has been a significant increase in this type of knowledge gained from experiments. Based on years of practice in animal experiments, early implantable devices for human applications were designed and manufactured to restore impaired auditory, visual, and limb motor abilities.

The main line of research is the brain's unusual cortical plasticity, which adapts to a brain-computer interface and can control the implanted prosthesis like a natural limb. With the current advances in technology and knowledge, pioneers in brain-computer interface research can convincingly attempt to create brain-computer interfaces that enhance the functioning of the human body, rather than just restoring the functioning of the human body. In the past, this kind of technology only existed in science fiction.

Two more news items:

Tesla and SpaceX CEO Elon. Musk announced his latest venture in March 2017: Neuralink, which focuses on brain-computer interface (BCI) technology. Initially, it will be used for medical research, but the ultimate goal is to prevent humans from being eliminated by AI and to advance the integration of humans and AI.

According to Musk, the main obstacle to human-robot cooperation is communication "bandwidth".

This means that using a touch screen or keyboard is a slow way for humans to communicate with a computer. To that end, its new company, Neuralink, aims to create a direct "high-bandwidth" connection between the human brain and the machine.

The U.S.-military's Defense Advanced Research Projects Agency (DARPA) last year announced a $60 million program to develop an implantable neural interface in collaboration with a range of private companies.

The project is part of former President Barack Obama's ambitious "brain plan." DARPA wanted a device that could record 1 million neurons simultaneously and stimulate at least 100,000 neurons. DARPA also wants the device to be able to transmit wirelessly, the size of a five-cent coin, and be ready for use within four years — an extremely aggressive deadline.

Potential applications for the device include the repair of vision or hearing problems, as the device can directly feed digital auditory or visual information into the brain. The exact technical method of the device is unclear, but the project is backed by some important engineering giants, such as Qualcomm.
