I use OOP every single day. I don't have the issues the author expresses. Am I doing it wrong? The answer is no. My yardstick is: when it becomes challenging, be pragmatic about it. We write code. We're not etching letters into concrete here. This stuff can change. Make a decision, move forward. When you know more, make a change. Every system can trigger indecision paralysis - OOP is no better or worse than any other at that, just different.
