I love the article's point, and I tend to feel that the "chasing the cargo cult of 'scale'" is maybe the biggest problem I see in development teams today. It is certainly the biggest problem that I rarely hear anybody talking about.
Author here. I would say that my post is less
targeted at someone like you (application developer,
presumably) and more targeted at library developers.
Reading the HN comments, I see that I'm not the only person who came away with a misunderstanding there.
Again, I 100% love the overall point.
