>Growth is driven by other factors, like when a brilliant but insufferable physicist moves back home to be close to his mother [2], and is a function of individual(.) This is true in the short term as the individuals already exist and their prior experience is already locked in. The long term problem is that of failure to create a new generation of high performing individuals, either through a collapse in birthrates (already underway for at least 1 full generation) or a failure to entice high potential individuals to participate in meaningful endeavors (arguably happening right now). Humans have a defined lifespan and their life trajectory is largely determined by outside factors even if their potential isn't.
