The original question, however, was a loaded one in the context it was asked, in that the person asking the question was using it to dispute the claim that individuals have biological limits that training cannot surmount. Even if this answer does not fully satisfy the excessively stringent terms of the question, it still works as a counterexample to the questioner's position.

Of course there are biological limits that training can’t surmount.

My point, more broadly, is that the idea that, “I can’t do that....genetics!” is misplaced defeatism.

For a majority of aspiring athletes, it is probably better for them to accept sooner rather than later that they cannot get to the first rank - and most of them do. Unrealistic expectations in either direction do not help (though a bias to optimism is probably a good thing.)

But, as I suggested earlier, I don't think the issue of athletic performance has much to say about creativity, which is the topic of this article. Indubitable's answer of Ramanujan is a much more relevant reply to your question, but where does that leave us? His example does not give us a reason to give up on creativity, which goes to show that the question doesn't address the issue.
