>Really? The device you're reading this on probably contains more complexity than it's possible for one person to understand in a lifetime, and that's one device. It wouldn't have been possible at all if the pieces that make it up weren't loosely coupled. >It's incredibly naive (or at best disingenuous) to assume that complex systems can be reduced by thinking and refactoring. It's naive to assume that you can't. Loose coupling pretty much only comes as a result of extensive refactoring.

...and one of the ways you can communicate such coupling is by diagramming the (complex) system's design. Google for "linux kernel diagram"[1]. It's quite well designed, displays loose coupling, high cohesion, and all the other things we like about good complex systems. If I want to dig in and start working on a module, I'd still have to understand the relationship between all the bits I work directly with (and probably some that are further away). Don't confuse loose coupling with low complexity. https://www.google.com/search?q=linux+kernel+diagram https://www.google.com/search?q=linux+kernel+diagram
