Die Welt ist flach: Eine kurze Geschichte des 21. Jahrhunderts

Friedman uses this metaphor to explain complex economic shifts, but I'm curious what prompted this particular analogy and how he developed it.

The book offers so many case studies, which can feel a bit dense. Did this approach help clarify the concept for others or make it harder to follow?

Friedman suggests significant changes ahead, but I wonder how much of it feels inevitable versus speculative. What are others’ thoughts on the outlook presented?
