Sounds like you've never worked for a CEO with "ideas." One time a CEO made the whole R&D team switch to "aspect oriented programming" because he had read a blog post. Another time we had to switch to C# because he had heard it wad better than Java.
Trust me, you don't want a CEO with "ideas."
I worked for a company with co-CEOs. The ideas CEO left and the company tanked. I think there's a right way to have an ideas CEO but maybe a balance helps keep them from switching everybody to C# on a whim. A CEO without ideas seems like a recipe for at best stagnation and at worse just fleecing the company of value and taking a golden parachute.
It’s 100% about the quality of the ideas, isn’t it.
I agree no ideas is just a path towards irrelevance.
The CEO doesn't necessarily have to have the ideas. How many ideas do you think Tim Cook had regarding products at Apple?
