Cómo funciona el mundo: Una guía científica de nuestro pasado, presente y futuro

Smil covers so many topics — I wonder what led to choosing this broad, analytical approach instead of focusing on one theme.

The book jumps between history, science, and economics, which kept me on my toes. Was this breadth intentional to challenge the reader’s understanding?

Given the vast subject matter, I’m curious about the selection process — what was prioritized and what was left out?
