It's also pretty astounding how big of a gap there is between even people at the very top, people high enough so that none of us could really tell the difference on our own. Ex: Jeff Bezos realized at Princeton that he was thoroughly outclassed by a small group of people in his physics classes who seemed superhuman to him - but lots of Amazon's employees have described him as a genius who corrects them on novel technical subjects he's never seen before. Likewise, at least according to Paul Allen, Bill Gates was intimidated by some of his classmates in the math classes at Harvard (in particular, Math 55), yet he's described pretty much universally as a genius with a frightening technical aptitude (who also came up with a novel pancake sorting algorithm as an undergraduate just days after learning about the topic).
