We will explain how object inheritance fundamentally obfuscates both your code and your clients’ code. We will explain how object inheritance forces your code to be more tightly coupled than it otherwise could be. We will present superior abstraction techniques and patterns that we use in place of object inheritance to make our programs easier to understand, use, extend, and maintain. We will explain how our pursuit of the loosest possible coupling of components has led us to adopt a new architecture pattern that we have humorously given the name “anti-Rumsfeldianism”.

Hi George! While we did a better job of delivering the talk at OSCON than we had at PyCon, the PyCon version was recorded whereas the OSCON version was not. You can find the PyCon recording at

Missed the talk, but very interested in the change of OOP. Is there a video? The slides are very difficult to follow
