Hierarchy and abstractions have costs, no doubt. I didn't get into that in the article, but the article was only 1500 words. I can imagine a long "yes, but..." section that explores the risks and downsides of small objects. It's possible to write total crap software using only small objects for sure. I don't advocate doing that. That's where the Bonsai metaphor comes in, that's as much about shaping and pruning as growing. Uncontrolled growth of small objects has a name: cancer.
