It’s not about developing superstars, at least not directly. It’s about developing a superstar team, which doesn’t have to consist of all superstars.
Think about sports teams and the draft. It’s not at all clear that a single or even a couple superstars is going to make for a winning team. Many superstars end up going nowhere with their teams because they are less of a team member and more of a showboat.
And I think that’s the heart of it; fostering a team environment where people are empowered and work well together is more important than having individual superstars on your team.
