Chip Stocks Crash, $20B Fund Margin Called, Frontier Labs: SLOW DOWN AI, Mamdani's Grocery Stores

Summary

The hosts discuss the crash in chip stocks driven by leverage and momentum, highlighted by a $20B hedge fund's margin call and massive liquidations in South Korea. They explore macro pressures from rising US long-term Treasury yields and persistent inflation, China's growing AI and semiconductor capabilities, and a petition from frontier lab employees to slow AI development. Additional segments cover book shredding for AI training data, New York City's new socialist grocery stores, and a science corner on fruit fly brain mapping revealing 64-dimensional network complexity.

• Chip stocks plunge as leveraged bets unwind, with South Korea seeing over a million margin calls and a 40% drop in the KOSPI.
• Leopold Aschenbrenner's $20B fund was margin called and its public portfolio sold to Citadel.
• The US 30-year Treasury yield crosses 5.2%, making government bonds attractive relative to high-valuation AI stocks.

• Employees of Anthropic and OpenAI sign a letter asking the US government to pace frontier AI development, sparking debate over regulatory capture.
• Anthropic is reportedly shredding rare books to obtain unique training data, raising legal and ethical questions.
• New York City announces five city-owned grocery stores offering 30% monthly discounts, framed as a socialist spectacle that could gain political traction.
• A fruit fly brain mapping study shows that modeling neuronal connections requires 64-dimensional space, hinting at the extraordinary complexity underlying consciousness.
