 The 23-year-old’s career didn’t exactly start auspiciously: He spent time at the philanthropy arm of Sam Bankman-Fried’s now-bankrupt FTX cryptocurrency exchange before a controversial year at OpenAI, where he was ultimately fired. Then, just two months after being booted out of the most influential company in AI, he penned an AI manifesto that went viral—President Trump’s daughter Ivanka even praised it on social media—and used it as a launching pad for a hedge fund that now manages more than $1.5 billion.

 But that also prompts the question: Why are so many willing to trust this newcomer?

 The answer is complicated. In conversations with over a dozen friends, former colleagues, and acquaintances of Aschenbrenner, as well as investors and Silicon Valley inside
