The biggest tell that Bob Martin isn't operating from direct experience and first principals is his 180 from object-oriented to functional programming. You don't get a dichotomy like that if you derived your opinions. The principals that functional programming is built on, what actually provides benefit to the program, would have gradually permeated the earlier teachings, they wouldn't just come out of nowhere and flip the entire ideology.

He's selling a product. He'll say what sounds convincing and he won't say things that are true but unpopular (or boring). I don't think it's deliberate but the end result is similar.

One point I do think is relevant though, is that smarter people and better programmers can cope with more complexity in one place. Carmack can probably cope with a lot more state/lines/whatever within a single function, whereas chunking everything up into a form digestible by 5-year-olds is sometimes necessary for your code to be approached by a junior. But the consequence of making dostoevsky digestible by children is that you either remove a significant amount of the content, or the book becomes hundreds of thousands of pages long. And it raises the obvious question, do you want your 747 designed by juniors?
