Highlights

The Great Stagnation thesis: innovation slowed down in the 1970s and we're only now catching up
Cowen argues that American innovation stagnated from roughly 1973 to 2020 — we picked the 'low-hanging fruit' of electricity, antibiotics, and automobiles, and progress slowed until AI.

Cowen and Klein discuss how falling birth rates across developed nations threaten the economic growth model that democracy, social security, and pensions all depend on.
