The human brain, the structural basis of its thinking and memory.

It is a neural network formed by nerve cells communicating with dendrites through axons and transmitting information.

Every synapse in this complex network can store about 4.7 bits of information.

And the world is dynamic, and so are human beings.

The nerve cells in the neural network of the human brain are constantly forming new synapses, and old synapses are constantly disappearing.

In particular, when humans are exposed to external stimuli, the number of synapses formed and disappeared increases suddenly.

These synapses usually last only a few hours, while others persist for a long time and have the potential to settle down to form new neural circuits.

When the neural circuits change enough, the neural network built by them will also change significantly.

As a result, the memory, thinking, and consciousness that exist on the basis of this network will also change greatly.

Only the total amount of information stored in the human brain will be relatively unchanged.

As for the total amount of information stored in the entire human brain, the so-called 'hard disk capacity', it is about 910 terabytes.

1TB, equal to bits.

Therefore, the total amount of information that can be stored in the whole human brain is bits.

That is, about 7.8 trillion bits.

On this basis, there are about 100,000 concepts that can be mastered by humans in various specific fields of knowledge.

This so-called 'concept' can be people, things, scenes, words, numbers...... Wait a minute.

For example, a top chess master can memorize and master about 100,000 games.

For example, Shakespeare has a vocabulary of about 29,000 words, and the meanings that these words can convey happen to be close to 100,000.

So, is this information storage capacity of the human brain considered large?

The answer is, not much.

In comparison, the information storage density of single-stranded RNA viruses is 200 million billion bits per gram.

In other words, the total amount of information stored by just one gram of single-stranded RNA virus is more than 2,500 times that of a human brain that weighs an average of 1,500 grams.

The microscopic structure design of the brain of the new human who has undergone the whole brain transformation of nano-neurons is based on the single-stranded RNA virus, and on this basis, it has also been greatly optimized, increasing its information capacity by nearly 4,000 times.

Therefore, the mechanical brain of the new human, even if it is only one gram of total information storage capacity, will be ten million times that of the old human brain.

Just one gram is such a huge disparity, and the general weight of the new human brain ...... It is 3,000 grams, which is twice the average weight of the old human brain.

Therefore, even without mentioning the 'giant brain' or 'multinucleate' new human elites who have switched to mental work.

The total amount of information stored by the mechanical brain of just the most ordinary new human individual is enough to rival the tens of billions of human brains of the old era.

At the same time, the total computing power of the old human brain was about hundreds of quadrillions per second, and if you add a certain degree of redundancy, then you can roughly calculate it into tens of trillions per second.

As for the new human who was artificially modified and 'born' on the basis of the old human, the computing power of the mechanical brain is about ...... A billion exabytes per second.

And with such a powerful memory and computing power, as well as the speed of sub-light neuronal information transmission.

The new human beings whose intelligence has undergone earth-shattering changes are even more powerful enough to make the old humans jaw-dropping and terrifying.

If we had to describe this terrifying gap in intelligence between the old and the new humans, we would only be able to use the term 'Superhuman Upheaval' to describe it in a rough way.

The so-called superhuman upheaval means that with the accelerated development of science and technology, human technology will reach a critical point.

Once this tipping point is crossed, supernormal intelligent entities such as strong artificial intelligence, hyper-network intelligence, and deep human-machine integration will be born in human civilization.

And once born, these super-agents will quickly self-reinforce and eventually open a new era.

At that time, all the rules of the old human era will be completely invalid and completely meaningless.

As for what kind of fate the old humans will usher in in the new era, whether they will be all extinct or soar with their thighs in their arms, it depends on the thoughts of these super-intelligent entities.

Although the concept of the so-called 'superhuman upheaval' is only a vague vision of the future of the old human civilization.

But the explosive intelligent leap of the new human race does reflect the old human being...... Almost no difference from chimpanzees.

Therefore, it is only natural that the new humans see themselves as a new and advanced species that is different from the old humans.

All the ethics, morals, and rules that belonged to the old era have also completely failed in the new human beings.

And everything of the old humanity has been completely abandoned by the new humanity.

Including, the carbon-based flesh and blood bodies of old humans.

In the future, about seventy centuries after Mu Cang's pause at this moment, all the new human beings who have completely completed the brain transformation have basically completed the 100% cyber mechanization of the entire body in just a few hours to a few days without exception.

The reason why they are so resolute is also because the new humans are extremely aware of it.

Compared to their fragile carbon-based bodies, only mechanical bodies can carry their vision of stepping into the sea of stars and their desire for immortality.

Although the mechanical body is not indestructible, when it is broken, it can be easily repaired or replaced by external forces.

Anywhere you want, you can find professional tools to disassemble the body, restore the deformed parts to their original state, and replace the parts that cannot be repaired in situ with new ones.

In contrast, flesh and blood are much more delicate, and it is very troublesome to transform, and if you are not careful, your life will be in danger, or you will have an unknown mutation.

Even if deep genetic modification is carried out, there are still risks and hidden dangers that are difficult to determine.

It is especially important that the rate at which individual genes evolve can never be compared to the technological progress of a population.

In this unsurprisingly strict materialist universe, it is obvious that the former is far superior to the latter in terms of the growth rate of the total amount of information and the rate of content change of a civilization compared with the growth and change of the genome information of a single organism.

What's more, the lifespan of flesh and blood has its limit, and it is impossible to be immortal.

In short, in that turbulent era of alternating between the old and the new, artificial limbs, artificial internal organs, alloy bones, extracorporeal auxiliary brains, magnetic hand knives, electrodynamic muscles, high-energy lasers, multispectral prosthetic eyes, multi-spectrum ear vortices, laryngeal acoustic cannons, nanomechanical insect nests, miniature antimatter engines, inter-arm particle laser cannons, kinetic energy vector deflection skin, abdominal micro-drone aprons, external armed mechas, and controlled interstellar spaceships...... A variety of large and small mechanical plug-ins with perfect functions and powerful effects have turned new humans into humanoid Gundams that can cut mountains and seas and fly to the sky, and the 'flesh' can break through the speed of sound, even hypersonic speed, and even sub-light speed, and can single-handedly kill through the modern nuclear society.

At the same time, while possessing such superhuman strength, the new humans have not lost all the hormonal senses of the old humans.

They can also enjoy the hormonal stimulation of food, wine, tobacco, coffee, sports, sex, etc., as well as the pleasure, refreshment and excitement generated by these stimuli.

And thanks to the help of high technology, the various hormones existing in the mechanical body of the new human are also artificial technological products that have already been deeply modified.

Therefore, these hormone-like products that have been removed from all kinds of negative effects can be fully enjoyed by new humans without bearing the slightest harm.

As for the old humans, who were unwilling to remodel their brains or mechanize their bodies from the beginning to the end, they were defeated by the new human group very quickly and overwhelmingly in a pan-solar system human civil war that represented the 'battle between the old and the new'.

After this humiliating defeat, some of the old humans who were willing to undergo brain remodeling had the opportunity to join the arms of the new humans and become part of it.

However, if the old human beings cling to the fundamentalist idea that 'flesh and blood are the real human beings', and are still stubborn and unwilling to accept transformation, they can only accept the cruel physical extermination given by the new human group.

One by one, they turned into invisible vapor under the high-energy laser beam.

But in addition to these two, there are some of the lucky ones of the old humanity who have fled to the distant Kuiper Belt, where they have made their home and survived, and survived day by day.

In just half a month, the new humans who quickly cleaned up the old humans and then fully received all the 'legacies' of the terrestrial human civilization in the old era developed a sub-light speed spacecraft that can rely on the momentum adjusted by the electric field and the momentum exchange of ionized particles in the interstellar space medium to produce a strong propulsion - the Swimmer spacecraft.

Not only can this spacecraft easily reach 90% of the speed of light in a vacuum, but its overall structure is also simpler and purer.

More importantly, the Swimmer ship is more likely to slow down than any previous type of aircraft.

This means that it is even more convenient.

After 'seeing' the future at this stage, Mu Cang stopped observing.

"It's a bit dry to just use deduction to 'see' the future, but it's better to ...... See for yourself. ”

With this in mind, He raised his right hand and waved it slightly.

Buzz –

Suddenly, this huge three-dimensional universe with a diameter of hundreds of billions of trillion light years rushed towards the future at great speed.

Whoa, whoa, whoa, whoa—

With the fierce change of time, the scene around Mu Cang was like a palette that had been overturned in an instant, and suddenly it became a mixture of colors and difficult to understand.

All kinds of vague and chaotic color blocks and turbidity currents, large swaths of flying and cruising in the four directions of the universe, constantly churning, constantly surging.

Mu Cang, on the other hand, stood alone in the staggered scenes of extreme chaos, waiting leisurely.

Waiting for the future.

Yes, He has accelerated time throughout the universe for a closer observation or viewing, the Earth-star civilization that existed more than sixty centuries later.

Whew-

Just a moment later, the time arrow, which was extremely fast forward under Mu Cang's will, was stopped by him for a second.

The 'timetable' of the solar system has also crossed 6,700 years to 8,800 AD.

No, it's two hundred years.

Hmmm-

The air waved, and a small silver-white shuttle-shaped spaceship thirty meters long slowly landed on the vast mooring platform thousands of meters away from Mu Cang's front.

Mu Cang remembers that it was a busy commercial area more than 6,000 years ago, with many shops and buildings in it.

Now, after a long time, it has become an empty tarmac.

"The power of time is so interesting, time flies and ......"

Mu Cang looked around, and after seeing a large area of green grass and undulating valleys, he couldn't help but smile and said, "The sea will also turn into a mulberry field." ”

These natural landscapes are beautiful at first glance.

But in reality, it is a 'pseudo-landscape' made up of endless nanomachines.

Of course, it is a bit too much to say 'fake'.

Because the landscape composed of green grass and trees all over the mountains is essentially a nano-artificial creation.

But with the cutting-edge technology of the new humans, they still have all the functions that 'pseudo-scenes' should have.

Photosynthesis, air purification, water regulation, soil and water fixation, and ecological ...... and so on, these nanomachines can do it.

And it will be better than real trees and plants.

But that's not really what these nanomachines do.

Its main function, or main purpose, is to live and entertain, scientific research and airship maintenance.

In other words, it is a 'building' hidden under the natural landscape.

Boom!

With the sound of mechanical collapse coming from the front, the spaceship parked on the platform suddenly cracked more than a dozen gaps regularly at the 'belly and waist'.

The gap widened and widened, and then it directly cracked into a huge hole two meters square.

From the 'hole' that glowed with blue light, more than a dozen mechanical tentacles hummed softly, curling a sturdy torso without a head or limbs, and slowly stretched out to a height of one meter from the ground.

Then, five more long mechanical tentacles, each carrying two arms, legs, and a male head, stretched out from the five directional cracks in the front, back, left, right, and middle of the silver-white spaceship above the 'human stick'.

And with the assistance of other tentacles, the skull, two arms and legs, one by one, were inserted into the bare broken neck, below the shoulders and in the hip gap of the "human stick".

As a result, the new human was immediately able-bodied.

"Fun way to drive."

The sight of a bunch of 'severed limbs' erupting from a spaceship and then combining into a full-bodied human being is indeed a bit frightening.

But Mu Cang in the distance knows it clearly.

This is the way of piloting a flying ship that was common to the new human group in the 88th century.

They like to disassemble their bodies into several parts and put them inside the ship, then connect their sensory perception into the main system of the airship, and finally use the first view to pilot the ship.
