Is this a matter of just learning, or some other factors? What are the prerequisites for the emergence of these individuals?
Let me be clear, by super talented individuals I mean those who had wonderful genius in interdisciplinary areas of science. For example Bu-Ali Sina had genius in variety of areas including medicine, philosophy, astronomy, alchemy, geology, mathematics, physics, logic, and psychology without having any previous prototype to learn from. He was able to cure patients when he was only 6 years old; this is not an ordinary talent. Another example is Plato whose areas of genius were in mathematics, logic, philosophy, ethics, rhetoric, religion and some others. I believe that the world sees these individual rarely.
