Object-Oriented Programming is all about dependency management. Dependency management is crucial for building evolving systems that survive and adapt to contextual changes.
It's a paradigm that scales. Even the new "container" based virtualization technologies such as Docker are basically treat "Operating System" as an Object. Even Javascript's "Revealing Module Pattern" is just making a namespace of bound functions...at some point when you're passing the same 3 parameters to 5 functions you start thinking "wait. What if I just passed those parameters to 1 function that called those 5?" and you're on your way to OOP.
Good OOP is about seeing the relationships between things and figuring out how things actually come together. Your software is a jigsaw puzzle, a Lego set. The principles of good software construction all come down to good dependency management.
When you see the right relationships, you minimize the dependency between unrelated things, form logical partitions, and find traversals through the object graph that you completely replace at sub-graphs without any loss of generality.
When you don't, you create bloated, bureaucratic, hard to read and understand systems that don't work. Hopefully at least they fail in obvious ways. It's far more difficult to fix when failures aren't obvious.
