That's a narrow view of the issue described in the blog post. You're coming at this from the perspective of a software engineer, which is understandable given the website we're posting on, but the post is really focusing on something higher level - the ability to decide whether the problems you're decomposing and the code you're reviewing is for something "good" or "worthwhile" in the first place. Claude could "decompose problems" and "review code" 10x better than it currently does, but if the thing it's making is useless, awkward, or otherwise bad (because of prompts given by people without the qualities in the blog post), it won't matter.
