Object Oriented Programming is Inherently Harmful

Object-oriented programming is an exceptionally bad idea which could only have originated in California.” – Edsger Dijkstra

object-oriented design is the roman numerals of computing.” – Rob Pike

The phrase "object-oriented” means a lot of things. Half are obvious, and the other half are mistakes.“ – Paul Graham

Implementation inheritance causes the same intertwining and brittleness that have been observed when goto statements are overused. As a result, OO systems often suffer from complexity and lack of reuse.” – John Ousterhout Scripting, IEEE Computer, March 1998

90% of the shit that is popular right now wants to rub its object-oriented nutsack all over my code” – kfx

Sometimes, the elegant implementation is just a function. Not a method. Not a class. Not a framework. Just a function.” – John Carmack

The problem with object-oriented languages is they’ve got all this implicit environment that they carry around with them. You wanted a banana but what you got was a gorilla holding the banana and the entire jungle.” – Joe Armstrong

I used to be enamored of object-oriented programming. I’m now finding myself leaning toward believing that it is a plot designed to destroy joy.” – Eric Allman

OO is the “structured programming” snake oil of the 90' Useful at times, but hardly the “end all” programing paradigm some like to make out of it.

And, at least in it’s most popular forms, it’s can be extremely harmful and dramatically increase complexity.

Inheritance is more trouble than it’s worth. Under the doubtful disguise of the holy “code reuse” an insane amount of gratuitous complexity is added to our environment, which makes necessary industrial quantities of syntactical sugar to make the ensuing mess minimally manageable.
