A lot of people claim that if we somehow managed to clone da Vinci he (most likely) wouldn't be as unique and special today. They argue that such a genius personality is a sum of infinite conditions that somehow made a guy brilliant.
Why would that be the case?
It makes more sense to me that being a genius is a successful attempt at fulfilling exceptional potential. Why should we immediately disband the hypothesis that da Vinci could have been an even greater mind if raised in an environment that would allow him to develop faster and easier? It doesn't mean he would necessarily accomplish as much as the original had of course.
All under the assumption that humans have individual potential but that seems obvious to me looking at Usain Bolt.
Question is: What's the reason not to clone da Vinci, or Einstein, or Newton?
