I think a human is completely unproductive.
The information like knowledge and know-how accumulated over 80 years of our life will disappear with our death.
A life is born naked, just in an initialized state like a personal computer or a cell phone.
After decades of trial and error, and deep learning like AI, we finally become a full human both physically and mentally.
Around the age of 30, we can at last get to a start line as a full human who functions as an adult.
The more the amount of information we have to learn to become a full human, the more the time it will take to learn such information.
Furthermore; such information has been accumulated by our predecessor day by day.
When the time it will take to learn such information exceeds our life span, it might indeed be a “singularity” in the sense of our human nature.
In any way, a human is just a creature. Therefore; such information acquired by a human can be neither saved nor installed like a computer.
Even our children who share our DNA could not be transmitted such information automatically.
From the point of view of AI, a human might be like a single cell organism, only just born and grown up and die.
Human evolution might not be a big deal for AI.
As far as a human is a living organism composed of organic matter, it could not be expected for further development or evolution that would surpass AI.
Moreover; a human body is too fragile and its life span is too short to explore the universe when viewed on a cosmic scale.
In Great Voyage Era, it might not have been a problem if our body is too fragile and our life span is too short.
However; when we explore the universe where no one has gone before, we could do nothing with our fragile body and our short life span as we have.
If all the information, which has been accumulated and built up by us, could be possessed and inherited in the form of data, it would become a kind of an intellectual life entity that would replace a human.
In a way AI could be a kind of an intellectual life entity in the near future.
In the science fiction, aliens still come to this earth in the form of creatures.
But that would not be possible.
If there were aliens that could reach this earth after traveling through hundreds of millions of light-years, they would be a kind of an intellectual life entity just like AI or like a kind of an information cloud, etc. which we could not recognize at all where they are or what they are.
Maybe they might already be on this earth just because we humans could not aware of their existence.
