The digest
Imagine being 24 years old, on your wedding day, celebrating with friends, family, and Silicon Valley's elite in Carmel, California. You've just married the person you love, and your hedge fund, started less than two years ago with $225 million, now manages a staggering $45 billion. But as you prepare to say your vows, your biggest investments are collapsing, and within days, $35 billion of your empire will be gone. This is the true story of Leopold Aschenbrenner, a young man whose wedding week became the biggest crisis of his career.
The AI Prophet
Leopold Aschenbrenner built his reputation on an audacious claim: he could see the future before anyone else. His hedge fund was aptly named "Situational Awareness." In June 2024, he published a 165-page PDF essay titled "Situational Awareness: The Decade Ahead," which quickly went viral in Silicon Valley. His central argument was that Artificial General Intelligence (AGI) was coming by 2027, and the world was unprepared. Investors, captivated by his foresight, sought him out.
Born in Germany, Leopold was a child prodigy. He skipped several grades, graduated from Columbia University as a valedictorian at just 19, and was even called an "economics prodigy" by economist Tyler Cowen at 17. His first job out of college was on the philanthropic arm of Sam Bankman-Fried's FTX empire, a position he held until FTX's collapse in late 2022. This wouldn't be the last company on his resume to make headlines for the wrong reasons.
From FTX, Leopold moved to OpenAI, joining the Superalignment team, which was tasked with figuring out how humans could maintain control over AI systems once they surpassed human intelligence. However, his tenure was short-lived. He was fired in April 2024 for allegedly leaking information. Leopold, however, tells a different story. He claims he was fired for raising concerns about OpenAI's security vulnerabilities to foreign actors, a memo that HR dismissed as "unconstructive." Two months after his firing, he published the essay that would launch him to fame.
