I read quite a bit about what the author wrote at google and worked with people that had worked with him. I only heard good things and he seems very smart. He wrote some articles that I remember was obviously wrong, and maybe this is one of them. That was usually when it was outside of his domain knowledge. Of course I could only recognize it when it was an area where I had a lot more local knowledge. I think very smart people sometimes overestimate how well they understand things they have not thought much about and underestimate domain knowledge. I think the same as him about crypto, but I also think I don’t know the domain very well and could very easily be wrong.
