Is a manager “good” if they’re not talking about your career growth? I disagree with the author on this point so the rest of it really doesn’t follow. Then again, he also had 20 managers in 18 years… so yeah I can see why none of his managers ever got around to asking about his career growth.

Even if any did, none could have done anything meaningful to push his career growth.

Absolutely. Good managers are invisible. They don't need to talk about career growth as they have already silently, in the background, removed any impediments that might have prevented you from growing. All you need to do is move in the direction you want to go.
