The one thing that worries me is the average person. The average person doesn't know and doesn't care about any of it. And when facebook, google, the government or whoever starts coming up with centralized systems that they control that look enough like a decentralized system to fool the average person then what? I think the majority are going to stick with the corporations like they always have. They trust companies even though they shouldn't because the idea of decentralized anything sounds scary to people not familiar with any of this and they don't have the intelligence, time, or interest to educate themselves. And I feel like for these things to truly work, the majority must be on board.
