Episode notes
Demographics Are A High-Confidence Macro Trend
- Demographic projections are unusually robust because they rest on births and deaths that change slowly over decades.
- Pictet forecasts dependency ratios above 50% in many developed countries within 20–30 years, sharply raising retiree burden.
Technology Is The Natural Substitute For Shrinking Labor
- Declining labor supply will reduce output unless substituted by something else in the production function.
- Robotics and AI can substitute scarce labor and boost productivity, altering gloomy demographic-only forecasts.
Invest Only Where Automation Meets Demand And Institutions
- Invest where automation can scale, where demographic demand persists, and where institutions support diffusion.
- Prioritize sectors with cheap, diffusable tech, skilled workers, and supportive infrastructure or regulation.
