I love the section about getting rid of Active Record only to discover that the handwritten SQL equivalent is unmaintainable and slower.

Also if you're on the fat-models team and you have lots of behaviors and business logic on your models, it's often easier to just go with Active Record, because the second you wander off the beaten path (e.g. handwritten joins) you start dealing with weird franken-models that contain attributes from multiple tables, but not their behaviors (methods, callbacks).
