"I'm not young enough to know everything" Having recently started mentoring/managing the first really junior engineer on our team (self-taught, <1 year programming experience), boy does this ring true. Luckily I'm of the temperament to find the "advanced beginner" stage of learning more funny than annoying. I think it's possible to understand as little about your code when using loggers as when using debuggers, so I have a hard time agreeing with him there. I think his general point about having tools and knowing when to use them applies just as much to that as it does to language, so he contradicts himself.
