Range: Why Generalists Triumph in a Specialized World

I enjoyed the book. The topic, the research, the details felt like they'd been written for me. Read for an understanding of the other view, opposing the early and hyper specialisation that rules the current social and business structures.
Yet, it was a slow, sluggish read. Shorter by a third, and it'd have been a crisp 5* book. Now I'm struggling to choose between 3 and 4.
