It's not difficult to ask Feng Guozhi about him, the difficult thing is that Feng Guozhi is the twenty-fourth filial husband and father, and he goes straight home as soon as he gets off work, except for part-time time, not a minute of his spare time belongs to him, I really don't know how Ah Nuan would suspect that such a husband would come out of the closet.

may be because he felt guilty in his heart, and Feng Guozhi did not hesitate at all about Lin Hai's invitation, of course, after agreeing to Lin Hai, he would definitely have to ask Ah Nuan for leave first, but Ah Nuan couldn't take care of him at this time, because Ye Xuexin came to see her goddaughter, and the couple had already planned it.

Lin Hai knows the habits of people like Feng Guozhi, so he doesn't look for any high-grade places, petty bourgeois sentiment is even more undesirable, please ask people like Feng Guozhi to find a fly restaurant, because this kind of place saves money, this is the place he should patronize.

Feng Guozhi apologized again and again for not sincerely thanking Lin Hai for helping them reconcile their husband and wife, and poured himself three glasses of beer in a row as an apology, Lin Hai was a little crying and laughing at this, but Feng Guozhi was really sincere.

So Lin Hai easily took out a lot of information from Feng Guozhi's mouth.

Feng Guozhi's work unit belongs to the kind of company that is less than the above, mainly engaged in disabled products, such as prosthetic hearing aids, etc., there are agent products and self-developed projects, Feng Guozhi is responsible for a wheelchair project, which is a high-end product, equipped with artificial intelligence, can be controlled in a variety of forms, including nerve extension, voice control and brainwave control, but also contains a variety of intelligent perception avoidance functions, the value of a wheelchair is more expensive than a sports car.

Of course, it is impossible for Feng Guozhi to lead the entire project with his qualifications, he is only the person in charge of the brainwave analysis sub-project of the brainwave perception project team, and it is precisely because of this that he has time to go outside to work part-time and help another company to build intelligent algorithms.

In other words, Feng Guozhi is a program ape engaged in software.

After listening to Feng Guozhi's introduction, Lin Hai suddenly realized that it was indeed the tragic profession of the programmed ape that was in line with Feng Guozhi's character and good habit of being afraid of his wife!

After pondering for a while, Lin Hai opened his mouth and said tentatively:

"Lao Feng, I'll consult you about something."

Feng Guozhi put down his chopsticks, nodded vigorously and said:

"Just ask."

"Well, you're researching brain wave sensing, do you think those science fiction novels can really achieve something like a brain helmet?"

"Brain Helmet? Ah, you said the two-way brainwave sensor used for virtual reality or augmented reality, right? That thing... According to the speculation in our industry, the most optimistic view is that it is hopeless in 20 years, probably the same as nuclear fusion technology, I am afraid it will depend on 50 years later. ”

Lin Hai pondered for a moment:

"Fifty years, when we... Well, he's eighty years old, hehe. ”

Feng Guozhi was stunned for a moment, and then laughed and said:

"yes, it's not dead anyway, as long as you use your brain, it's no problem, probably we can really catch this last train, haha."

"Oh, what's the difficulty?"

Lin Hai asked seriously, Feng Guozhi looked at Lin Hai a little strangely, but he didn't open his mouth to ask Lin Hai about the purpose of asking these questions, but thought about it:

"There are about three directions in this difficulty, one is the sensitivity of the sensor, one is the method of brainwave interference, and the last one is my business direction, brainwave decoding and coding technology."

"In other words, all three directions need to be broken through?"

"Yes, but the sensor is slightly better, because the existing technology can barely be used if the volume is not considered, but brainwave interference is difficult, and now there is almost no ready-made theory, and it is still in the exploration stage..."

Lin Hai remembered a brain research project led by the Institute of Cultural Strategy that he had visited, and remembered that there was a study of brain interference, and it seemed that their progress was not as Feng Guozhi said, and there was no theory, in fact, they already had a relatively systematic interference theory - bioelectrode implantation interference technology.

Although Lin Hai didn't know if that technology was feasible or not, and whether there were any sequelae, but according to the urine of that institute, they wouldn't care about any sequelae, in other words, the three difficulties Feng Guozhi said, in fact, two of them no longer exist in a sense.

In other words, the final level is the brainwave decoding and coding technology that Feng Guozhi is tackling!

Lin Hai sighed secretly in his heart, Hu Xiaomei and the others must have known this key for a long time, and it was exactly this that she told herself at the time, but she omitted all the relevant pre-information, if she didn't delve into this matter, I am afraid that they would not have thought of Feng Guozhi's value, and they would have already grasped it.

On the other hand, if Lin Haihai knew that he wanted to pursue Hu Xiaomei, he would not be able to talk about it, because Hu Xiaomei had already told him the truth at that time, but his understanding ability was limited, so he didn't grasp the key.

This Hu Xiaomei, as expected, is also an old official, and she doesn't leak anything when she talks and does things!

"Well, what's the difficulty of the decoding and encoding technology you mentioned, oh, if it involves the principle of confidentiality, I won't ask."

Feng Guozhi smiled and waved his hand:

"There is nothing confidential about this, it is a well-known thing in the industry, the decoding and coding technology of brain waves is how to read the information contained in brain waves, brain waves are actually very complex, especially people's thoughts move very fast, and the jump is extremely strong, the amount of information contained in it is too large, and the form and frequency of fluctuations are extremely complex, and it is quite difficult to interpret accurately."

Lin Hai nodded:

"Understandably, but how are you doing now?"

"We? Our company is not the first echelon, the most advanced foreign research can probably interpret the repetition of simple fixed words to this extent, we can still interpret a few thoughts... Mindfulness is our term for the repetitive desire to act in the brain. ”

"Repetitive desire to act?"

"Yes, such as 'move forward', 'stop', 'call for help', etc., we use some simple training to let the machine intelligently read a person's brainwave habits, and then can control the wheelchair assistance activities according to the strong desire in the brain to drive."

Lin Hai looked very surprised and curious, and continued to ask:

"I probably understand what decoding and encoding mean, so what's the difficulty of this decoding? Is it to analyze brain waves? ”

"Hmm... I think the difficulty here is probably the relationship between brain activity and brain wave formation, in short, an algorithm. ”

Lin Hai thought for a while and said:

"I remember that brain activity is linked by many regions, such as the logic area, the image area, the memory area, or something..."

Feng Guozhi glanced at Lin Hai in surprise, nodded and said:

"Yes, it is precisely because it is multi-region linkage, so in a thinking process, the areas that generate brainwaves are also different, and the retrieved memory content, logical judgment content, result-driven content, etc. interfere with each other, so it will produce such a complex brainwave record, which also infinitely increases the difficulty of interpretation."

Lin Hai suddenly said:

"I see, I probably understand when you say this, this is a fluctuation formed after multiple levels and multiple sources or even infinite superposition, so the complexity is quite amazing."

"Well, that's about it."

"But with the speed of our computers now, can't we even use cloud computing?"

"This... Perhaps, but isn't it pointless to use huge computing resources to interpret a person's brainwaves? I think one of the key points to solve this problem is the re-emergence of computing power, multiple breakthroughs, and the discovery of more effective decoding algorithms. ”

Lin Hai suddenly felt in his heart, he probably understood what Feng Guozhi had discovered and was being targeted, most of which was what he called the decoding algorithm.

Seeing that Lin Hai nodded silently, Feng Guozhi hesitated for a moment and asked:

"Brother Lin, what are you asking for, do you also want to engage in this industry, or do you want to invest in related technology industries?"

"Haha, it's not, I'm a literary editor, I have a science fiction author in my hand, I wrote a science fiction novel about the widespread use of brain sensing technology, I heard A Nuan talk about your work, I think I can learn from you, at least it looks like there is no logical problem when you write it, and it can also bluff readers."

Feng Guozhi suddenly laughed:

"I see, if you need it, I can help you collect some popular science information."

"It would be nice if it wasn't troublesome."

"There's no trouble, our company has a complete set of these materials, and the market keeps up with the latest technology updates."

"Huh? Your company also does science popularization work! ”

Feng Guozhi pouted:

"! That's all for investors, and there are officials who are officials, and the bosses above also rely on these popular science articles to fool the board of directors. ”

Lin Hai laughed when he heard this, and Feng Guozhi also thought it was very interesting after speaking, and the two raised their glasses and touched one.

After drinking until more than nine o'clock, the two went back happily and went to report to their respective wives.

Lin Hai and Ye Xuexin have finished washing, and it is not too hot to nest together in the sofa.

Lin Hai reported the information collected at night to Ye Xuexin, Ye Xuexin listened carefully, thought for a moment and said:

"It seems to be the algorithm Feng Guozhi said, but according to Feng Guozhi, even if there are two other difficulties that have not been overcome with the algorithm, then the value of his algorithm cannot be reflected."

Lin Hai's face sank slightly, and he shook his head and said:

"No, in fact, those two problems should not be a problem anymore."

Ye Xuexin is so smart, she suddenly said when she heard it:

"The state has mastered the key technologies of the other two technical difficulties?"

"Yes, I don't know much about it, but it should be like this, just..."

Ye Xuexin looked at Lin Hai's face, thought about it and then persuaded:

"Husband, there are some things we can't control, we can only do it as well as we can."

Lin Hai was stunned for a moment, then sighed and smiled:

"You're right, in fact, those technologies may not be very reliable, but human life doesn't seem to be that important for huge interests, and we can't control it, let alone guess it myself."

Ye Xuexin smiled, patted Lin Haihuan's hand holding her, and said softly:

"Look at it another way, and more people will be grateful for their sacrifice."

Lin Hai smiled bitterly:

"Also, as far as I know, those people are voluntary, maybe I should really thank them, hehe."

Lin Hai smiled coldly, and then he quickly erased these inexplicable emotions, after all, he is not a virgin, and he can't do anything, maybe as someone said, in the face of the interests of the race, what do personal gains and losses calculate, if you want to be a virgin, let the awakening rate of the earthlings reach the standard as soon as possible, or don't be that boring virgin.
