>Really now?
Um, yes? Are you challenging the article's claim here? Depending on how strictly we're defining "game changing", only a small handful of people, even those who were "gifted" as children, ever accomplish anything really notable.
You can look at this [1] followup of "mathematically precocious" youth, for example. Around 10% ended up tenured at a top-50 university or became CEO of a Fortune 500 company. It is unlikely that anyone in the other ~90% is doing anything "game changing". Not even everyone in that 10% group is doing something "game changing".
