Launch HN: EdotEnv (YC S26) – Quant Trading RL Envs to Teach LLMs Research

Models must act under partial information, committing before full consequences are observable.
Static worlds produce static intelligence; dynamic environments are essential for model improvement.
Markets do not saturate but become more efficient with successful trading, requiring continuous adaptation.
Trading success involves multi-step planning and balancing short-term vs. long-term gains.
Decisions affect future paths through exposure, opportunity cost, and unacted choices.
A model succeeds by recognizing regime shifts before consensus forms.

Focus on the objective, not the implementation.
Early decisions are made with limited information and should not be treated as sacred.
Sunk cost is inevitable, but rigidity is optional.

Business logic often follows 'when something happens, something else should happen' pattern.
Coupling facts and consequences in a single script obscures the domain fact and creates maintenance issues.
Domain events record facts in past tense, not commands; they are immutable and contain enough information to identify the fact.

World models, unlike large language models, learn dynamics from observation and simulate outcomes to predict behavior in the physical world.
Key figures like Yann LeCun, Demis Hassabis, Sam Altman, Fei-Fei Li, and Jensen Huang are advancing world models through different approaches, though definitions vary.
Current AI applications in Earth science (e.g., fire detection, weather forecasting, flood prediction) have improved but struggle with complex systems like hurricanes and the carbon cycle.

Confidence in beliefs can grow monotonically only in a static world; change undermines that certainty.
Experts often fail because they rely on outdated knowledge about a changed world.
Successful startup investors recognize that good ideas often seem bad initially due to recent changes.

Labs bet that training AIs on millions of verifiable tasks across diverse RL environments will lead to AGI by developing general problem-solving skills.
Data inefficiency and lack of continual learning can be overcome by scaling, similar to LLM breakthroughs.
In-context learning may replace weight updates if context windows become arbitrarily large.
