The Architecture of Everything
Stop seeing isolated objects and start seeing the invisible webs that connect them. Learn to decode the feedback loops and emergent patterns that govern everything from your kitchen to the global economy.
Like Duolingo, but for The Architecture of Everything. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Seeing the Hidden Web and Navigating Complexity. It assumes you already know the basics.

Key ideas in The Architecture of Everything
- Objects are temporary snapshots of ongoing interactions between components
- Stocks are the measurable amount of a resource at a specific moment
- A system's identity comes from the functional connections between its parts
- Flows are the rate of change that increases or decreases a stock over time
- Changing one relationship can transform the entire nature of the 'object'
- A stock only stays stable if the total inflow equals the total outflow
- Recognizing that objects are actually dynamic systems of relationships
- Distinguishing between accumulating stocks and the flows that change them
- Boundaries are mental models chosen to make a specific problem manageable
- Causal loops involve delays that hide the long-term effects of a choice
- Narrow boundaries often hide the external causes of internal problems
- Expanding a boundary can reveal new solutions by including more stakeholders
- Identifying the sequence of a 'fixes that fail' causal loop
- Reinforcing loops amplify change
- System boundaries are mental constructs
- Balancing loops create stability
