Businesses, Math, Music, Go, Chess, IQ tests, Poetry, Physics, Early development, and sculpture don't really have all that much in common.
... except for the people who excel at them. The author of this article is a mathematics professor and an author. I'm a computer scientist and a violinist. And in my time reviewing entrance scholarship applications for my alma mater, I don't think I've ever seen a student who excels in a single academic field and has no other unusual talents or accomplishments.
It takes more to be outstanding as you get older, so a 10 year old can be outstanding in several of them. And a collage student may keep up with 3 or 4.
However, none of the worlds best people in any of those, as in top 5, is also the worlds best any in any of the others. Not to step on anyone toes here. Michael Jordan was an incredible baseball player as in better than 99.99% of everyone that has ever played the game and by the 1:10,000 concept he may have been a dual genius, but that was not enough to be outstanding at the top level. And that is for two vary closely related sports.
So sure you can be outstanding in 2 or 3 of them but good luck finding people that can play at even just the professional level in Go, Physics, Sculpture, AND Poetry.
PS: My point is that collectively they don't share much in common. The Music / Math link while strong is not the same as the Music / Sculpture link.
I agree with your post, however, there are exceptions. While Jordan didn't have the best baseball career, Bo Jackson did excellent in both football and baseball.
Bo Jackson won't make the Hall of Fame in either of those sports, let alone both.
IMO, making the Hall of Fame is one obvious/indisputable mark of someone who is truly distinguished by excellence in the sport. (He did make the All Star & Pro Bowl, but those are far less distinguished honors, with something like 5-10% of players making those teams each year. So, rather than being a "top 5" type of mark, it's a "top 68" (baseball) and "top 110-ish" (football).)
