Rob Wiblin interviews Tyler on *Stubborn Attachments*

Episode Summary

Executive Summary: Tyler Cowen and Robert Wiblin discuss Stubborn Attachments, centered on the moral importance of sustained economic growth, long-term future generations, stability, and environmental risks. The conversation repeatedly weighs consequentialist reasoning against human rights, uncertainty, and practical political constraints, while also ranging over nuclear risk, AI, genetics, addiction, climate change, philanthropy, and the limits of space colonization.

Main Topics: Economic growth as the central moral objective (Priority: 5/5): Cowen argues that maximizing sustainable economic growth is the best macro-level way to improve welfare over time, because growth compounds and benefits both present and future people. Longtermism, uncertainty, and the value of the future (Priority: 5/5): The discussion explores why distant future generations should count morally, how small changes can ripple across history, and why uncertainty does not eliminate the importance of long-run consequences. Rules, rights, and limits on consequentialism (Priority: 4/5): Cowen defends a largely consequentialist framework but insists that human rights constrain what can be justified, even when growth or stability might be increased. Civilizational stability and existential risk (Priority: 5/5): They debate nuclear war, surveillance, great-power conflict, climate change, genetic engineering, and other threats that could interrupt long-run prosperity or lock in bad outcomes. Markets, institutions, and policy activism (Priority: 4/5): The conversation covers liberal institutions, the role of markets, when law should be respected or resisted, and how individuals can actually raise growth or resilience in practice. Philanthropy, generalism, and public intellectual life (Priority: 3/5): Cowen explains Emergent Ventures, defends generalist writing and commentary, and discusses how academics, podcasters, and readers can allocate attention more usefully. Nonhuman welfare, nature, and moral pluralism (Priority: 3/5): They touch on animals, factory farming, wild-animal suffering, art, and whether moral realism can handle comparisons across very different beings.

Key Arguments: Economic growth matters because gains compound over time; even small sustained differences create enormous long-run welfare effects. The future should not be discounted morally the way financial cash flows are discounted; time alone does not reduce moral value. A person-first approach to philanthropy and innovation matters: talented people and unusual projects are often more important than rigid project selection criteria. Rules are valuable because deviating from growth-enhancing norms carries high long-run costs and creates avoidable error. Human rights still constrain action; not everything can be justified by long-run benefits, especially gross abuses of persons. Civilizational stability is closely linked to growth, because stagnant societies are more vulnerable to conquest, collapse, or political decay. Wealth generally raises welfare through happiness, health, technological progress, and spillovers to poorer societies. Nuclear war and accidental escalation are more plausible existential threats than climate-driven extinction, though climate can still cause major harm and bad policy responses. Centralized surveillance can increase stability but also strengthen authoritarianism and make bad regimes more durable. Space colonization is desirable in principle but likely far less feasible, near-term, and valuable in practice than enthusiasts claim.

Data Points: Average civilization duration: 400 years - Cowen cites this as the average endurance of civilizations in the context of stability risks. U.S. growth rate mentioned: 2.7% year-on-year - He describes current U.S. growth as weak compared with past performance. Climate-related mortality from air pollution: 6 to 7 million deaths per year - He uses this to argue that current pollution kills far more people than climate change itself presently does. Chance of human extinction/collapse in 100 years: Extremely small / below 1% annual nuclear risk implied - Cowen says the 100-year extinction risk is very small and nuclear risk is below 1% annually. Chance of severe civilizational regression in 1,000 years: At least 10% - He gives this as a rough estimate for a return to an earlier, much poorer stage. Historical growth comparison: A percentage point lower over 1,000 years would leave us in extreme poverty - Used to illustrate how small growth differences compound dramatically over long periods. Pakistan? No; China and India growth reliance on trade: Not quantified - He notes that richer countries purchase exports and transfer technology that benefit poorer countries. Climate damage estimate cited: 3 to 4% of global GDP - He references the London Report estimate while arguing the bigger danger may be our response. Global population modal forecast: Around 10 billion people for centuries - His rough expectation for population stabilization and eventual decline.

Pivotal Quotes: "what can we do to boost the rate of economic growth? ... make civilization more stable? ... how should we deal with environmental problems?" — Tyler Cowen: Cowen identifies the three macro questions he sees as central in Stubborn Attachments. "we can already see that three key questions should be elevated in their political and philosophical importance" — Tyler Cowen: He explains the book’s core normative agenda around growth, stability, and environment. "the moral rate of time discount should be zero" — Tyler Cowen: He states his view that future welfare should not be morally discounted simply because it is in the future.

Implications: Listeners are encouraged to think more long-term, support institutions and policies that raise growth and stability, treat future people seriously, and remain cautious about technologies or political systems that could lock in catastrophic or authoritarian outcomes.
