In my experience, the greatest teachers rarely have the official title "teacher". I learned more from one programmer in 5 months working with him than I did in my entire computer science degree. (And no, I'm not saying professors or degrees are useless, just that I don't think title's and reputation necessarily tell you much about how much a person will teach you.)

And honestly, reading "Uncle Bob's" advice, I find a lot of it is outright bad (here's a good breakdown: https://qntm.org/clean ), or specific to Java's quirks, or has no actual backing other than that Bob think's it's a good idea.
