I read a lot of books about military history. One thing that seems to come through, whether I'm reading about Roman legions 2,000 years ago, Napoleon 200 years ago or more recent battles, is that different branches of the military all denigrate each other. The air force, for instance, always believes that air power alone can win wars. The infantry believe in the primacy of their branch. And so on.
Similar dickering takes place everyday within the walls of ad agencies. The social media people believe in social media. The digital people believe in apps and digital experiences. The TV people believe in commercials.
What's important to remember in both sorts of sectionalism is that most often it takes a synergy of forces to prevail.
I'm tired of this shit. And may take a few days off.
