But Steve Jobs himself didn't do any of the engineering or design either, so...isn't he a people manager himself? And didn't he bring success to his company?
When managers don't make decisions, and instead leave up to their staff to make decisions, what is their job then? "Managing"? Meaning, sitting down on 1:1s every week and act as a face of the team, do yearly reviews and assign safety training courses?
Intelligent and skilled workforce should not waste their time reporting to these people who have no vision or spine of their own.
