Counter point: most people operate on workloads so trivial that they don't need optimized. I think the most important line in the article is the "let's see how far it gets us." It is absolutely trivial to invent situations where an architecture wouldn't work well, or scale, or "be optimal." It's far, far harder to just exist in reality, where most things are boring, and your "bad" architecture is all you ever need.
