That was my initial reaction when I saw the post, but then I realized how often very knowledgeable and level-headed people share and discuss very deep topics on HN. It's possible there has been less of this as HN has grown in the last few years, (I'm more than a decade old on here), but there are definitely people who understand this topic very deeply. Even software engineers. People who don't get all they know from 30 second news snippets.
