You've read his writing outside this blog post? Or is this a first-impression take (in which case the degree of negativity would be a little unexplained)?

There is no negativity in my previous message, and I have read some of his writing on DDD a long time ago, so this is not a first impression. In fact, at the time I did not find anything wrong with his DDD writing, but I also didn't know much about him. It's just that in general, I have experienced at numerous instances consuming a piece of content, and later out of curiosity investigating the author's background, and finding out that they had no credibility to back up the authority they were claiming. Even in person, I have seen people go up on stage, spout complete nonsense, especially about AI, and having the crowd cheer.
