Wow, who expect that a modern business leaders can learn from the Rome Empire. This quote: "They were just incredibly good at co-opting people and ideas” also remind me other multicultural army - Austro-Hungarian Empire Army befor the I World War. The Rome Army united everybody: Rome citizens and also a other folks (e.g. Lacjum peoples). This was also Austro-Hungarian Empire strategy - amalgamate everybody around one common idea. Great example of huge, team leadership (how "infect" others team members).
