At Google there's a culture of promotions and accolades being handed out for starting innovative shit, but not much for properly maintaining those initiatives. It's why they have all these products that die after two or three years, and why some of their executives made the jump from IC to management without knowing how the hell to sustainably manage. A good engineer can almost always be a good manager, but there are definitely some who simply can't or who don't get a proper crucible before being placed in a management role.
