From another comment here, and his own words to describe how he arrived at his vision, it sounds like he's walking around his own factory and realizing it's set up very inefficiently. I mean, maybe he just figured this out, but it does sound a lot like "shoot first, ask questions later" being spun into a positive. Or, in less polite terms, "Not everybody's factory processes are as messed up as Tesla's."
