I believe we are all geniuses in one way or another. Sometimes it is a matter of luck whether one's genius is discovered and also valuable. There are people who are "super recognizers" meaning they can see a face once and always remember it. These people are highlightly sort after by police departments, many super recognizers do not realize they are genius at this particular skill -- assuming that everyone was like them.
Being genius at putting a inflated ball through a hoop, 10 feet off the ground, is a very valuable skill today but completely useless for most of humanity's time on Earth.
Einstein was both smart and inspired. As a theoretician he had to be really good at math but it was his thinking out the box really set him apart allowing him literally rewrite the laws of physics by intuiting the warpage of space/time -- something that escaped another genius, Newton.
