Definite optimism as human capital | Dan Wang
Economists treat innovative capacity as a fixed stock waiting for the right policies, but imagination and optimism are forms of human capital that must be actively cultivated—through proximity to manufacturing, earnest sci-fi visions, and resisting the psychological damage of recessions.

TLDR
• Innovation requires an "improving mentality" that must be inspired, not just incentivized—people need to imagine technological futures before they can build them
• Manufacturing decline removes tacit knowledge and imaginative capacity from society; when you lose electrical engineers, fewer young people study those fields, creating a downward spiral
• Recessions cause deep psychological scars that damage long-term growth: Japanese millennials choose stability over wages 15+ years after their downturn; CS graduates didn't recover to 2001 levels until 2014
• Many service jobs are asymmetrically zero-sum: one hacker forces billions in security spending, one fraud case spawns thousands of compliance jobs—unlike manufacturing which builds technological capacity
• We need earnest, optimistic sci-fi and cultural products that expand imagination about the future, not endless dystopian narratives about technology killing us
In Detail
Dan Wang argues that economic models fundamentally misunderstand innovation by treating it as a fixed stock of capacity waiting to be activated by policy. Instead, he proposes that "definite optimism"—concrete imagination about the technological future—should be considered a form of human capital. Innovation requires people to first have an "improving mentality," which must be inspired through exposure to industrial processes, science fiction, and proximity to manufacturing work.
The decline of US manufacturing isn't just about job losses—it represents a loss of tacit knowledge, design expertise, and imaginative capacity. When a state loses jobs for electrical or mechanical engineers, fewer young people study those fields, and technological development slows. Manufacturing work, despite being unpleasant, exposes people to industrial processes and builds capacity for technological upgrading in ways that service jobs don't. Many service jobs are asymmetrically zero-sum: a few hackers force companies to spend billions on security; one fraud case spawns thousands of compliance jobs. Unlike manufacturing, these jobs don't build toward a technological future.
Recessions may damage long-term growth more than economists recognize by creating lasting psychological scars. Japanese millennials, scarred by decades of stagnation, choose stability over higher wages even in a tight labor market. Computer science graduates didn't recover to 2001 levels until 2014—a 15-year hangover from a brief recession. If recessions reduce risk appetite and optimism for generations, they're far more costly than standard models suggest. Wang calls for cultural interventions: fund earnest, optimistic science fiction instead of dystopian narratives; create world fairs showcasing technology; make industrial processes exciting. The goal is to expand imagination about what's possible, treating optimism as an input to growth rather than just an output.
