How close are we humans to immortality?

 The question of human proximity to immortality has been and still is the focus of long and deep studies by different scholars and from different fields.

However, a consensus has been reached by some of these experts and observers on the answer to this question.

Scientist Ray Kurzweil and his followers all agree that humans are 20-25 years away from being able to live as long as they wish.

But what will enable the inhabitants of the earth to achieve this? Kurzweil, one of those notable for observing human advances in recent history [read his book on technical singularity The Singularity Is Near], believes that the key to immortality is nanotechnology.

Given the direction in which computers are evolving and are constantly getting smaller and more efficient, people will then be able to carry small robots in their veins to clean and provide permanent maintenance of blood and cells.

Kurzweil also assumes that robots will replace our organs when they fail and become exhausted, and these developments would mean that as long as robots are powered and work well, humans will be able to survive and extend life.

Kurzweil's predictions have previously been proven to be far from inaccurate.

He successfully predicted the year in which the smartphone would appear and its capabilities, and described the Internet before it was even invented.

Kurzweil convinced his colleagues in the scientific community of his hypothesis about human immortality.

He calls his theory the law of accelerated returns [what is meant by acceleration is the exponential growth of technological development which in turn 'returns' to industries with greater efficiency and lower cost].

He explains that through nanotechnology, humans will be able to halt and reverse the aging process.

He thinks small robots will be exponentially more efficient than normal human cells.

He also predicts that the achievement will not be limited to achieving immortality, but will enable us to accomplish tasks that are impossible for humans with normal biology.

Imagine, for example, running an Olympic race for 20 minutes without taking a breath, or diving into the depths of more than four hours without oxygen.

With the addition of extra life and the development of our brain capabilities, Kurzweil also indicates that small robots will be able to enable humans to do things that are difficult for our species today, such as writing an entire book in a matter of minutes!

Kurzweil says, describing how the world will change around us, as small robots in human bodies, for example, will be able to change their perceptions and create virtual worlds in their consciousness, and the virtual sex will become familiar and 3D hologram characters / visualizations will appear before us as if they were real.

He also states that we humans should aspire to a world in which we become cyborg [a term given to an object that combines natural biological organs with a machine, such as Arnold Schwarzenegger's role in the terminator] and to be immune to the threat of most of the diseases we face today.

To those who claim that humans should not celebrate immortality because immortal life will bring with it boredom and despair, Kurzweil says that "immortality" is a wrong term to describe these developments.

Immortality means that it is impossible for anyone to die, an inaccurate description in this case, as humans with nanotechnology will still be able to die.

Dying unintentionally would be unlikely, but leaving life would still be available for whoever wanted it.

Nor will the human will be at stake.

However, humans are close to immortality!
