It seems to me the great differentiator is risk-taker vs. risk-averse, not so much "smarts." The examples given in this article, Elon and Zuck have both been wildly successful at some endeavors(Tesla,SpaceX,Facebook) and have failed spectacularly at others (Twitter, Meta-verse) But they both are risk-takers. And on a long enough time-line even seemingly successful "masters of the universe" will fail at some point in their careers. What one then hopes is that you collect enough wisdom on your journey to make fewer mistakes as you go.
