That's an entirely circular argument and doesn't prove anything about Uncle Bob.

Question: Why should I listen to Uncle Bob? Answer: Because he wrote a book telling you what to do.

He's got some un-controversially good opinions but he also has some opinions that are just plain stupid. Since his opinions don't compile and aren't testable, it's not easy to rate their over all value.

It would be circular but for the word useful, which implies that, at least for some people, including me, some of what he said compiled and worked..
