Disagree completely. A good project manager sees themselves as a peer to devs, with a goal of shielding their team from dumb administrative stuff (like requests from upper management that are clearly out of touch with how the product actually works).

To do so, they must see themselves as a peer. Anyone with an ego who wants to boss people around will be a terrible PM. A good PM enables their team and is altruistically driven.

Once you work with someone like this, you'll understand how amazing PMs can be.
