Episode notes
Industrialize Model Building
- Build a factory to produce and iterate models continuously instead of betting on a single technique.
- Invest in plumbing so new papers and data can be adopted fast to preserve advantage.
Replayability Before Explainability
- Explainability will follow once models achieve replayability (deterministic, repeatable outputs).
- Stable, replayable decisions are a precondition for regulatory-safe AI in finance.
Prefer Principle-Based Regulation
- Favor principle-based regulation that forbids discrimination, not prescriptive technical rules.
- Use regulation to speed the market toward fair, consumer-protecting equilibria.
