Something that always strikes me is that people underestimate the impact of a decentralized world. Especially more vulnerable people that depend on society for ‘survival’.
You shouldn't worry about it because 100% decentralization will never happen. Decentralized systems need to be perfect. But guess what, human beings ain't perfect. We are far from being perfect. We make mistakes and sometimes mistakes need to be "fixed"
Since it is not going to work with the decentralized systems, it is never going to get super big in the future.
Being perfect simply don't comply with the HumanOS.
