Episode notes
Neighbors Turned Colleagues
- Arden and Hannah live a block apart and often walk to the same workplace, creating frequent informal interactions.
- That proximity lets Arden show up casually on the podcast and boosts local community dynamics.
Marginalism Can Scale In A Big World
- Marginalist advice can still scale to large audiences because the world is vast and needs many marginal interventions.
- AI work spans many tasks, so focusing on AI doesn't necessarily exclude broad participation.

- Use public, low-bar actions (e.g., targeted tweets) as effective collective CTAs when actors are responsive.
- Mobilize simple tasks that leverage visibility and responsiveness of tech leaders.
