Sarah Paine - Why Russia and China can't escape geography
Geography constrains strategy. Sarah Paine’s lecture frames continental land powers versus maritime trading powers and highlights how Russia’s strategic posture can target global agriculture. The resulting food-security risk premium supports selective exposure to agricultural commodities and inputs as a beneficiary hedge.
Linked assets
Key tickers tied to the thesis: DBA (broad agriculture ETF) for diversified exposure to rising crop prices and input demand; MOS (fertilizer producer) for leverage to higher planting incentives and input pricing; NTR (diversified crop-inputs) for broader fertilizer and crop-input exposure; WEAT (wheat futures ETF) for direct sensitivity to Black Sea supply disruptions and higher wheat volatility.
Broad agriculture exposure for geopolitical disruption hedging.
Fertilizer leverage to higher planting incentives/input pricing during food-security cycles.
Diversified crop inputs exposure; benefits if farmers increase spend amid elevated crop economics.
Direct wheat sensitivity if Black Sea supply risk resurfaces (higher volatility).

The primary source is a lecture-level geopolitical framework contrasting continental land powers and maritime trading powers. The talk notes Russia/Putin’s targeting of global agriculture as a strategic lever. The content is conceptual and maps to tradable ideas only through second-order implications: defense spending, supply-chain resilience, and agriculture/food-security risk premia.
The source is a physics/GR discussion (Einstein’s equivalence principle, inertial motion, free-fall vs acceleration) with a brief anecdote about Jane Street traders; it contains no market, macro, company, sector, earnings, product, regulatory, or pricing information that would support a tradable investment view.

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
