Because the idea that all the engineers that work at his large company are morons is absurd. Anyone in that situation that believes that and even more, states it, is just making their own character flaws apparent.
It’s hyperbole, like a teacher complaining to others, “my kids were all crazed animals today.”
I’ve worked with engineers where I had to wonder how they found their computer every morning. I can easily see how a few of those would make you bitter and angry.
