What I find so obtrusive about OOP which I feel is a massive issue (maybe has to do with the last sentence in Joe's post). OOP is pushed into places it does not belong and causes a lot of impedance issues.

OOP developers want if something doesn't talk OOP then to make it talk OOP, for example ORM's and SQL databases.

It is a tables and sets, most of computers use sets and tuples, yet OOP needs to be serialized and abstracted away and pushed in almost becoming a data type in it's self.

And I think there are other issues and pervious failures like this.
