To me, genius is more a particular point in time where someone has the intelligence, aptitude, drive, and time to put something together of staggering importance. Any of those qualities could recede just as quickly as they were brought on. I suppose if one is a considered a "genius" during these times, they could be called a "former genius" after them. Though once you're recognized it seems polite to forever hold the title, kinda like President or something.
