Invasive brain-computer interface devices require electrodes to be implanted into the cerebral cortex to obtain neural signals, which can easily lead to bacterial infections. Therefore, the FDA has been reluctant to allow Neuralink to conduct large-scale human trials.

The human brain is constantly sending out neural signals, which are captured by motor sensors. However, there is a lot of "noise" that prevents the device from accurately recognizing the true intention of the human brain.

Zheng Li's method is to extract the main signal through filtering algorithms and Fourier transforms, and then analyze it in combination with the ocular nerve signals to determine its true intention.

Neuralink's approach is to implant electrodes into the human brain. If the cerebral cortex is not enough, they will be implanted even deeper into the skull.

This method is extremely harmful to the human body.

Musk was even more furious: "Why did you tell me four years ago that non-invasive brain-computer interfaces were impossible when others had already achieved results?"

"You spent 150 million US dollars, and so far you've only succeeded in experimenting on pigs and monkeys?"

Neuralink has completed its Series A and Series B funding rounds, with the majority of the funding coming from Elon Musk, raising a total of 158 million US dollars.

Hordak murmured, "Synchron has only conducted experiments on animals. Non-invasive brain-computer interfaces have not been very effective before, so the mainstream companies in the industry have not been researching along this route."

Synchron is Neuralink's counterpart, and the market values ​​the two companies roughly the same.

Unlike Neuralink, which aims to expand into the consumer industry, Synchron focuses more on three medical verticals: nerve repair, nerve modulation, and nerve diagnostics.

Musk asked seriously, "Why did we implant thin-film polymer probes into the human scalp last year, and this year we've turned it into a coin-shaped miniature device?"

Neuralink's new product in 2020 requires the removal of a small piece of a person's skull before implanting a micro-device.

It's much more radical than the 2019 version. Hordak explained, "Because last year's film polymer was a flexible material, the implantation surgery was very complicated, and the implantation failure rate was close to 10 percent."

"Although our new device requires cutting off a small piece of the skull, the difficulty of the surgery is actually reduced."

Musk asked, "If you were a customer, would you choose Kechuang Bio's brain-computer interface product or our brain-computer interface product?"

"Compared to science and technology innovation, we have no advantage whatsoever."

Hordak shook his head violently: "No, we still have a chance!"

"According to statistics, the brain-computer interface of Kechuang Bio has a recognition rate of 70% in European and American languages."

"Once we understand their technical methods and follow their technical approach, we will be the first to achieve a 99% recognition rate for European and American languages."

"We will succeed. Kechuang Bio dominates the Chinese market, while we dominate the European and American markets. In the field of brain-computer interfaces, we still have room to survive."

Kechuang Bio's brain-computer interface devices are mainly used in the mobile phone industry. Synchron does not overlap with their main business. However, Musk's Neuralink is Kechuang Bio's direct competitor in the field of brain-computer interface.

Musk: "You are still here talking to me because you still have a chance."

"Regarding the technology of Kechuang Biotechnology, I had SpaceX's lab conduct preliminary research. They have made a breakthrough in chips; their chips can filter out noise from neural signals first."

"Then there's the algorithm. The standardized API they provide processes the signals collected by the chip into neural signals that are closest to the user's true intentions."

"Algorithm engineers speculate that Kechuang Bio has adopted a brand-new algorithm that combines commonly used algorithms such as sparse representation, discrete wavelet transform, and Fourier transform."

"Since the sample provided by Kechuang Bio is a closed package, decoding will take time."

"You guys conduct research on the chip first, and we'll figure out how to bypass Kechuang Bio's patents to develop a similar chip."

"I will leave the algorithm entirely to SpaceX. You can form a collaborative team to work together on this."

"In addition, we can try to recruit researchers from Kechuang Biotechnology; we need to know their technological roadmap."

"One year, I'll give you a maximum of one year!" Musk finally roared.

Neuralink has a very strong technological foundation, and Musk gave it a year based on the premise that they could understand the technology roadmap of Neuralink.

Hodak seemed to remember something: "Danny Lee, the head of the research department at the Sci-Tech Biotech Singapore R&D Center, was previously the leader of a research group in our company."

“We can dig him back.”

Musk agreed, saying, "Sure, if he's willing to come back, give him the position of head of the R&D department."

Major tech companies in America have all received samples from Apple.

Apple organized a team to test the product as soon as it was received, and the results were amazing.

Apple itself found that it couldn't unpack the program and there were many aspects of the chip that it didn't understand, so it specifically sent it to relevant technology companies, hoping to use their expertise to crack the secrets of Kechuang Bio.

"There's still time before the iPhone 13 is released, so we can definitely add a brain-computer interface to the iPhone 13. An iPhone that can be controlled by the brain would be a revolutionary product!"
