> She's the CEO of Yahoo. That's not a "waste of a good brain".
How can you be sure? What a CEO of Yahoo can do? Hire some people, fire some people? Pick some project to develop and some to abandon? You could say that this has some value but you can't predict which project will turn out worthwhile. "Predictions are hard especially about the future." What's sure that there is one smart person less actually working on those projects.
This logic is also applicable to engineers. Everything an engineer could potentially do has value, but you can't predict which project will turn out to be worthwhile. And without someone smart managing them, I'd assert there's a higher probability of that, which wastes everyone's potential.
