I'm not confusing anything. OOP is a horribly OOT over-engineering of a problem looking for a solution, from the get go. That it morphed and twisted into a bloated mess when it was taken up by people who didn't get it to begin with is just the inevitable result of starting with a big pile of no need to do all that in the first place.
The sad truth is that most great ideas are doomed to drown in a sea of mediocrity and misinterpretation.
