Episode notes
Feasibility Of Universal High Living Standards
- A global economy eight and a half times larger by 2100 is feasible with 2.6% annual growth driven by compound progress.
- McKinsey framed it as an existence proof comparing poorest countries to Switzerland and found physics and resources are not the main barriers.
Resource Limits Are Expanded By Technology
- Resource scale-up is achievable because reserves and extraction improve as demand rises, not just because deposits are fixed.
- Example: since 1950 we extracted 800M tons of copper but added 900M tons to reserves through better discovery and processing.
Petri Dish Rebuttal About Limits
- Bradley recounts a biologist's Petri dish objection and counters it with two 'magic' properties of Earth: size and growth.
- He notes more than half of GDP happens on under 1% of surface and the planet grows ~1–2%/year, extending usable 'edge' space.
