I agree, but in my opinion, that's not about greatness, but about mindset and your understanding of your role. You don't need to be great or write very smart code to get there, you just need to have "somebody must be able to take this over if a bus runs me over tomorrow" and "I want to solve this and move on, not managing it to become my permanent job" as guiding principles when you approach problems. I've seen a very smart developers get fired recently, because he was hogging responsibility and became a bottleneck precisely because he figured that would strengthen his position in the company. "If they need me, they can't fire me". Once "they" figure that out, they will really want to fire you, and if the pain you cause is greater than your value, they will. And it usually always is greater if you're a bottleneck.
