- Labor share
- The fraction of total GDP paid out as wages and salaries to workers, as opposed to returns to capital; has hovered above 60% in most developed economies for centuries.
- Capital share
- The fraction of GDP paid to owners of capital — machines, land, buildings, and equity — rather than to workers; complements labor share to sum to roughly 100%.
- Kaldor fact
- A set of empirical regularities about economic growth observed by economist Nicholas Kaldor, including the remarkable long-run stability of labor's share of national income.
- Relational sector
- Goods and services where the human presence in the production process is itself part of the value — e.g., a human therapist or barista — not just the output.
- O-ring theory
- A model of production where the weakest link determines overall quality, inspired by the Challenger disaster; used here to explain why partial AI automation may not yet be viable.
- Lump of labor fallacy
- The mistaken belief that there is a fixed amount of work in an economy, so automation permanently destroys jobs rather than allowing new tasks and sectors to emerge.
- Conjoint analysis
- A survey method that asks respondents to trade off between product features to reveal their underlying willingness to pay for each attribute.
- Demand elasticity
- How sensitive the quantity demanded of a good is to changes in its price; highly elastic demand means a price drop leads to a more-than-proportional increase in quantity purchased.
- Jevons paradox
- The counterintuitive finding that making a resource cheaper can increase total consumption of it by so much that absolute usage rises, first observed for coal in 19th-century Britain.
- Investment-specific technical change
- A form of technological progress where the price of capital goods falls relative to consumption goods, so a given amount of investment buys more and more productive capacity over time.
- Universal Basic Capital
- A policy proposal where every citizen receives an ownership stake in productive capital assets — like a diversified stock portfolio — rather than cash transfers.
- Negative income tax
- A tax system where people below a certain income threshold receive supplemental pay from the government rather than paying taxes, effectively providing a guaranteed income floor.
- Wealth tax
- An annual tax levied on the total net worth of individuals, as opposed to income or consumption taxes; debated as a tool for redistributing AI-generated wealth.
- Network-adjusted factor share
- The share of value added by capital or labor in a good when you trace the entire supply chain, not just the final production step.
- Dissipation shock
- A term used in growth economics for events that disperse concentrated wealth — like an heir spending down a fortune or a billionaire donating to a foundation.
- Von Neumann probe
- A hypothetical self-replicating spacecraft that uses local resources to build copies of itself, used here as a metaphor for a maximally greedy self-replicating optimizer.
- Satiation
- The point at which additional consumption of a good yields no further utility; used here to describe whether rich people or AI agents will ever 'have enough' capital.
- Sovereign wealth fund
- A state-owned investment fund that holds financial assets like stocks and bonds on behalf of a nation, proposed here as a mechanism for developing countries to index into AGI returns.
- Neuralese
- Informal term used in the episode for the internal representations or communication protocols native to AI systems, which humans cannot natively read or participate in.
- Leapfrogging
- When developing economies skip intermediate stages of technological adoption and jump directly to the most advanced technology, as happened with mobile banking in parts of Africa.
