The author does not have public contributions to verify his coding skills(no github), think before you invest your time to read the long article.
You, on the other hand, do not have a GitHub account tied to your HN account, or any other records of your achievements, for that matter. You also don't seem to have made any meaningful contributions. But people still took the time to read this comment.
The author's history of contributing to OSS projects shouldn't be relevant here. You shouldn't use it to attack his claims. If someone wants to read the article, they can read/evaluate it based on their personal opinions/knowledge.
