Anyone foolish enough to get a computer in their brain will likely get all of their memories harvested by ai bots. Getting ddos attacks on brain would likely cause death.
Unfortunately, humanity will most likely have to integrate part of its brain with a shared knowledge database and with AI.
The database will definitely be useful. AI support (I prefer the term expert systems) can also be useful. However, a lot depends on the method (methods, technical solutions) of this integration. It will certainly not be widely available for a long time, due to the cost (and perhaps various risks).
And there are many preconditions for this. One of them is that the amount of knowledge required for normal life activity is becoming more and more with each generation. If ~500 years ago it was enough to be able to count and read/write to be an educated person. But now you have to spend 11 years in school (in my childhood only 10 years), then 5-6 years in university, and then only at ~24 years to start moving up the career ladder.
Because it is related to the development of civilization. That is why people specialize even within one field (mathematics, physics, chemistry, etc.).
For a woman's body in general, this is sometimes catastrophic. All doctors say that the biological time for a woman to conceive a healthy child is before the age of 25. What kind of study or career can she have then? Especially if she wants to have time to find a good husband and give birth to more than one child before 25.
In technologically advanced countries, women don't want to hear about having children. And as for potential husbands, they have astronomical demands. This is simply the result of the rise in the standard of living caused by technological development. Few are interested in challenges. It has always been that way.
Alexander the Great died at the age of ~32, having already conquered a large number of ancient states.
Jesus Christ died at the age of ~33, having become wise enough to change history for the next 2000 years and more.
Only that Alexander the Great was an adventurer. In his time, there were many like him (strong competition between leading males within one group but also between different groups in grabbing resources). Secondly, medicine was practically non-existent at that time.
As for Jesus - it is not known whether such a person existed, there are practically no traces, except the testimonies of his followers. But it is possible that there really was someone like that (those were the times when many different religious reformers appeared, not only of Judaism). And such people always had strong opponents. Suffice it to mention what Mani's fate was.
And today's university graduate is just starting their career at 24-25 years old. And if person is a doctor, then he/she still has 1-2 more years of internship to study.
Yes. As a result of civilization development, there has been an increase in knowledge. And this forces adaptation of those who want to actively participate in the life of the community.
Anthropologists say that the human body in general is originally designed for an maximum 40 years.
It was rare to live past 30. Either tribal warfare, or disease, or being killed by an animal while hunting, and so on.
And this is how our ancestors lived for hundreds of centuries. An indirect confirmation of this is teeth which in many people begin to seriously deteriorate after 40 years even if they are well cared for.
And women can and physiologically should give birth right from the age of 13-14. What kind of long study can there be?
Well, there are many different views related to human biology and anthropology. On the one hand, there is the problem of the physiology of the body, the wear and tear of organs, errors in the functioning of cells with age. On the other hand, there is the issue of the development and functioning of the brain. Recently, about 2 months ago, I watched an interesting podcast with a professor of neurology (prepared by a fairly young physicist, a popularizer of knowledge on YouTube). The professor talked about the issue of brain development, about the so-called brain maturation. That human brains mature quite late. The extension of life (including thanks to technical development, which allowed for the development of medicine) has facilitated the significant development of humanity over the last centuries. This was one of the factors (not the only one) that accelerated the development of humanity. As you rightly mentioned earlier, for many millennia, people rarely lived to the age of 40. As a result, they were not able to accumulate enough knowledge and then use it. From a certain point, very slowly, human life began to lengthen. But this started to happen only a few centuries ago.
We can change this either genetically (live ~300 years) or we can integrate learning directly into the brain via implants.
And I suspect that implants will appear sooner than genetic longevity.
But these are not the only ideas. There is also a third one - nanomachines. This is why biologists and biochemists study viruses and simple single-cell organisms. They look at how they are built. Because they want to create something (nanomachine) that could repair cells and consequently rebuild organ tissues. The road to this is very long, but research is being conducted.
