In a completely decentralized world there would be chaos, people always talk about the advantages of Decentralized world but failed to look at the disadvantage, for people to come to consensus about issue is something that is very difficult to achieved, just look at the crypto space and see what happens with the BTC scaling issue.
Not exactly. If decentralized solutions prove to be rock-solid in maintaining the world's stability, then there should be nothing to worry about. Since Blockchain and AI are relatively new, they still have some limitations that need to be addressed over time. Despite their limitations, they can become a powerful workhorse being able to enforce the law and keep track of everything as they improve over time. Still though, a decentralized world may take some time before it becomes a reality. Even so, it seems to be more than a dream than anything else as governments and central banks are still in control.
As long as these entities exist, a decentralized world will be far from happening anytime soon. In the bright side, people will still have the choice of performing transactions and interacting with each other without middleman. But, centralization will always be there no matter how hard we try to fight against it. It's great to see how far Blockchain technology has reached, despite seeing much oppression from governments worldwide. Bitcoin, being the world's first cryptocurrency, is still facing scalability issues. The Lightning Network is far from being adopted by the mainstream world, as it's not ready in development yet.
Nonetheless, time will tell us the fate of our world as new technologies emerge which prove to be a great complement towards Blockchain tech. Just my opinion
