The problem is when you take out mistakes, there's not much left of OOP.

We take out 'dog-is-an-animal' inheritance.

We take out object-based delegation of responsibility (an object shall know how to draw itself). A Painter will instead draw many fat structs.

Code reuse? Per the talk, the guy who stumbled onto this was really looking for a List<> use-case, (not a special kind of Bus/LinkedList hybrid. He was after parametric polymorphism, not inheritance.
