Really? I don't think Steem needs Zuck of Steem. What we need is more cool apps that people will want to use regardless of leaders and regardless all those who shit on Steem. If we have something cool and unique that runs on Steem and it goes viral enough people will not care much is it centralized or decentralized, but that is a start and that is how they would learn about decentralization and what it means, how the ball starts rolling.
Also agree with your point about islands. Would be cool decentralized "united" in a sense to fight the dinosaurs.
