We are trying to replicate perfectly working systems that have been doing so since the beginning of living organisms, and we are learning.
Little by little we improve and develop more advances, and without sinning to believe ourselves, gods, we are achieving and will continue to achieve great things.
The human body is impressive and is a perfect model of engineering, nature in general is.
The problem is that evolution is very slow and we have to help it.
