Summary of the Key Points
This article discusses how brain-computer interfaces (BCIs) have moved from science fiction to reality: multiple hospitals in China have established BCI clinics, and medical insurance covers part of the costs for certain procedures. However, BCIs are currently mainly used to help patients with paralysis or amyotrophic lateral sclerosis (ALS) regain basic mobility functions such as eating and making a fist. They are still in the clinical trial phase. The article addresses common concerns regarding costs and potential security threats, such as hackers potentially gaining access to the systems. It also highlights other technologies like exoskeleton robots and AI glasses that are helping people with disabilities, emphasizing the significance of technology in bridging the gap between cold code and human emotions.
1. Brain-Computer Interfaces Are Not “Super Cheats” – They’re Tools for Helping Disabled People
Current BCI systems do not have the ability to download knowledge from the brain as depicted in science fiction movies; they are primarily used to help people who have lost their mobility regain some control over their bodies. For example, Mr. Yang, who suffers from high-level paralysis, was fitted with a BCI the size of two coins. By using brain waves to command a robotic glove, he can now eat and play the piano on his own.
However, not everyone is eligible for such a procedure: hospitals have strict criteria. The motor cortex of the brain must be active (in patients with long-term paralysis, this area may have atrophied, making it difficult to detect relevant signals), and the patient’s physical condition must be suitable for the surgery. Additionally, they must be motivated to undergo rehabilitation training after the operation. Only about 10% of those who consult the hospitals are actually eligible for the implantation.
2. The Costs Are More Complex Than You Think
The prices quoted by medical insurance (e.g., 7,980 yuan for installation and 3,500 yuan for removal in Beijing) only cover the surgical procedures (craniotomy and stitching). The cost of the devices is covered by research projects since they are still in the experimental stage. Once commercialized, the prices are likely to be higher, similar to cochlear implants, which range from 200,000 to 300,000 yuan. BCI technology is even more complex, with electrodes that are hundreds of times thinner than human hair, requiring significant investment in research and development (involving multiple disciplines such as materials science and artificial intelligence). After all, you wouldn’t want to send something that expensive through your brain just by clicking a button!
3. Hackers Cannot Easily Access Your Brain-Computer Interface
There’s no need to worry about hackers remotely controlling your actions, such as ordering a榴ian fruit. Medical-grade BCIs are very secure:
- The signals transmitted are one-way: they only read brain waves but cannot write data into the brain (so they can’t insert advertisements or alter memories).
- Even if the signals were intercepted, they would be meaningless since each patient’s brainwave pattern is unique and requires a specific decoding algorithm.
- In the worst-case scenario, any unauthorized changes would result in the robotic glove moving randomly, which can be easily resolved by removing it.
4. Other Technologies Are Also Helping People with Disabilities
Brain-computer interfaces are just the beginning of a revolution in helping people with disabilities:
- Exoskeleton robots: These devices act like mechanical prostheses, assisting paralyzed patients in standing and walking by using sensors to interpret movement intentions and motors to support their knees and ankles.
- AI glasses: They can help visually impaired individuals recognize faces, read menus, and identify traffic signals.
- AI sign language interpreters: They enable deaf people to communicate with others without the need for writing or speech aids. Cameras capture sign language and convert it into text or speech.
5. The Fascinating Power of Technology
The truly compelling aspect of technology is its ability to connect complex algorithms and chips with human emotions. These technologies help people achieve small, yet meaningful goals: allowing paralyzed individuals to light a cigarette on their own, ALS patients to hold their loved ones’ hands, or visually impaired people to know what’s inside the fridge. On one end, there are advanced technological advancements; on the other, there are real-life improvements that significantly enhance people’s quality of life. This is where technology becomes truly powerful: it brings back lost abilities and turns the impossible into possible.
