I’ve met one who asked me a question like this and he’s still at Apple having been promoted several times to a fairly senior position. But the question was only half hearted because the question was “how much CO2 would we save if we made something 10% more CPU efficient” and the answer even at Apple’s current scale of billions of iPhones was insignificant.

So now you and I both have come across such a manager. Why would you make the claim most engineer’s don’t come across such people?
