Sarah Paine - Why Russia and China can't escape geography

The index measures the performance of the aerospace and defense sector of the U.S.

Diversified exposure to defense primes/suppliers; better theme expression than single-name timing.

Broader participation across the defense supply chain if spending widens beyond a few primes.

The company operates through four segments: Aeronautics; Missiles and Fire Control (MFC); Rotary and Mission Systems (RMS); and Space.

Large program exposure aligned with long-cycle deterrence priorities.

RTX Corporation, an aerospace and defense company, provides systems and services for commercial, military, and government customers worldwide.

Missile defense/munitions demand tends to persist in multi-theater tension environments.

Lecture-level geopolitical framework (continental land powers vs maritime trading powers) with a brief mention of Russia/Putin targeting global agriculture. Mostly conceptual; only loosely translatable into trades via second-order implications (defense spending, supply-chain resilience, agriculture/food security).

Podcast description discussing economics of AGI: taxation/redistribution of AI-generated wealth, how non–AI-supply-chain countries share gains, and whether inequality explodes. Contains sponsor mentions (Jane Street recruiting; Google Gemini). No concrete near-term catalysts or company-specific fundamentals in the text.

What rebuilding AlphaGo teaches us about self-play, RL, and future of LLMs - Eric Jang Eric Jang walks through how to build AlphaGo from scratch, but with modern AI tools. Sometimes you understand the future better by stepping backward. AlphaGo is still the cleanest worked example of the primitives of intelligence: search, learning from experience, and self-play. You have to go back to 2017 to get insight into how the more general AIs of the future might learn. Once he explained how AlphaGo works, it gave us the context to have a discussion about how RL works in LLMs and how it could work better – naive policy gradient RL has to figure out which of the 100k+ tokens in your trajectory actually got you the right answer, while AlphaGo’s MCTS suggests a strictly better action every single move, giving you a training target that sidesteps the credit assignment problem. The way humans learn is surely closer to the second. Eric also kickstarted an Autoresearch loop on his project. And it was very interesting to discuss which parts of AI research LLMs can already automate pretty well (implementing and running experiments, optimizing hyperparameters) and which they still struggle with (choo
