An idea can be called genius. Often it requires knowledge and experience and coincidence for a genius idea (innovative idea, wise idea, disruptive idea).

Often it requires many years of efforts to create or to discover something new or great or genius.

From https://en.wikipedia.org/wiki/Genius:

A genius is a person who displays exceptional intellectual ability, creative productivity, universality in genres or originality, typically to a degree that is associated with the achievement of new advances in a domain of knowledge. Despite the presence of scholars in many subjects throughout history, many geniuses have shown high achievements in only a single kind of activity.[1]
