Artificial and Robotic Men Taking Over a Million Years Later
There must be hundreds of scenarios about how the mankind will be exterminated, since first of all the mankind is living things to go extinct some day and not a kind of Angels that were given eternal life by the God, and every specie of living things on the earth has been exterminated for some reasons or others in millions of years after its establishment. Indeed, there are no species of living things that have survived billions of years since the beginning of history of living things on the earth. Truly, nobody thinks that the species of the mankind will survive forever. Even this solar system will collapse in about 5 billion years. So, there is no wonder if extermination of the mankind has really started with this 2020 corona-virus pandemic although the 1918 Spanish-Flu did not trigger it.
But material science and technology will be further accelerated, so that it will be possible to freely manipulate the biological aspect of a man. DNAs and genes of a man will be engineered to prolong his life time at the maximum, although it is currently said that there is a limit of human life around 120 years due to the limit of survival capacity of each human cell. The limit on life time of each cell in a man will be modified, so that it may be able to undergo cell division in twice, 10 times, or million times the current number of times of about 60. Then a man will be able to live for 200, 400, or 1,000 years. All the old cells coming to the limit of survival may be replaced with new ones.
However, as long as a man is a human living thing, he should be subject to biological conditions. In future, it must be necessary to abandon biological bodies to further increase men's life duration. Because biological bodies can be sick or damaged physically or biologically due to viruses or bacteria. So, men will adopt robotic bodies that are free from any biological illness and infection and that may even withstand radioactivity and food-supply crisis.
If all the other organs are replaced with artificial or robotic ones, one specific organ remains: the brain. Most of brain cells constituting cerebral nerves are not reproduced, regenerated, or replaced. Since the birth of a man, the amount of cerebral nerves is basically not changed. But as time goes by, the number of connections (synapses) of each cerebral nerve increases, for example, from 04. trillion to 0.8 trillion in one month after the birth and to the highest of 2.4 trillion in eight months, and then decreases to 1.2 trillion in 10 years and finally is settled there.

(horizontal axis: years after birth; vertical axis: trillion connections)
It must be difficult to realize this growth of the brain and its nerve cells. And if artificial brain cells are created or robotic brain cells are built, it is another matter if these engineered brain cells and nerves work as those of a natural human being. And if super-advanced technology allows structure of natural brain cells are copied into artificial brain cells, it is dubious that the copied brain can work as the original natural brain without a natural body.
However, the mankind will solve this problem, taking thousands or millions of years. And they will succeed to transfer a natural brain into an artificial brain. Then, complete artificial men will be created by men. But, there is no assurance that artificial men keep tradition of natural men. Such an artificial man that has obtained almost undying body and brain may not need any legacy of the mankind.
Such men will stop keeping artificial human bodies that would restrict their ability of existence, movement, and wok. They will cut off any brain functions related to human bodies to further develop their artificial brain. So, it is unknown what forms they will take. And, it is also unknown what society they will build collectively.
Maybe this new specie of artificial and robotic men may live as long as this universe exists. But it is also unknown in what state this universe will fall finally. When every material collapses and gets vanished in this universe after uncountable number of years, such artificial and robotic men should also disappear.
Or will artificial and robotic men be able to govern the universe and change the law of the universe for them to survive forever, although it is not the business of the species of natural men, us?
Anyway, if the species of the mankind should disappear, say, for a maximum of a million years, artificial and robotic men will take over with some memory and legacy of the mankind for some time. But human believers of the God will be allowed to enter Heaven and obtain eternal life. For them, anything material, including this material universe, will have no meaning.
And implanted minds of natural men into artificial and robotic men must also want to enter Heaven and get eternal life.
