Nyeah ... but people can get promoted for consistently shipping stuff that works, on time. And people can get sidelined for consistently taking 10x as much time to provide the same business value. That may not be the rule, and it may not always be obvious in the short term who is sidelined. But it can happen.

It can even happen that the tag "very smart" gets attached to those sidelined engineers. That's not necessarily a compliment.
