Exceptionally talented people are born so; talent cannot be cultivated.

Exceptionally talented people are born so, talent cannot be cultivated. Some genetic scientists opine that talent is determined by the genetic factor. It is inherited genetically. It cannot be cultivated . Had it been so, it would have been possible to produce exceptionally talented people by grooming individuals. But in reality that is not the case.

Another perspective:

There are other group of scientists who believe that talent is not exclusively determined by the genes or heredity. Environment plays a vital role in shaping talent. They call it meme and not gene.
