@vacatio What I am (clearly) saying is that I have no way to evaluate what he says about those subjects. But people say he's an expert on them, so I assumed he was right.

Now he's saying stuff about building production software and everything he says is wrong as hell. However, the same people are insisting he is a genius. Since I know better, I now know that they say that about him no matter how dumb the things he says are, so they are not reliable testimony.
