He Shut Down a ByteDance Training Run. Now Investors Have Given Him $30 million.
In June 2024, a program stopped running on a training server inside ByteDance’s commercialization technology department. The person who stopped it was Tian Keyu, then a master’s student at Peking University and an intern at the company. He told Bloomberg the program was occupying GPUs, and he thought his own research mattered more. He admitted the conduct was wrong. He also called it “enforcing justice on behalf of heaven.” ByteDance called it “maliciously attacking the model training task.” A court ruled that he violated his internship contract. He paid 500,000 yuan and lost all his internship wages. ByteDance said rumors of 8,000 cards and tens of millions of dollars in losses were severely exaggerated.

The 72-Hour Death of a 24-Year-Old AI Genius
The last week of July 2026. An unnamed secondary market trader sits in his New York apartment, watching three screens. Ice melts in a glass. The market is falling, like a freight train with no brakes. At 3:04 PM, he sends a message to a friend: "Someone's unwinding. Big. Don't know who yet, but the bid is loosening." He doesn't yet know who that someone is: twenty-four-year-old Leopold Aschenbrenner, a former OpenAI superalignment researcher who wrote that long essay about AGI timelines, the young man who managed a $45 billion hedge fund and will vanish from public markets three days from now.

Introduction I was not sure where this should go. As you know, I collect vinyl records, but often buy them if they have exceptional artwork. Also, some have become sought after and rare on vinyl, especially early Krautrock albums. I recently captured "Dance Of The Lemmings" by Amon Düül II for £25, but you can check it on eBay and Discogs for what it is going for now.

What No One Tells You About Becoming a Quant
The first lesson for a beginner is never about strategy. It’s the window on Jukuan where he just downloaded daily frequency data. The cursor blinks at the end of the first line of code.
