This makes the assumption that “raw intelligence” is all that’s required to push at the edge of “hardest fields” This is simply not true. Some fields require learning 10-20 years of domain knowledge before one can push at the edge. Another factor is discipline, often the young are impatient, and lack the rigour and discipline required to execute. I think that the large leaps made by the young are through fresh ideas made from new perspectives, their minds unburdened with legacy methods. I’m not arguing that human intelligence peaks at young adulthood, I’m arguing that contributing to “hardest fields” is NOT simply a factor of raw intelligence like your answer assumes.
