It’s continually amazing to me that people listen to people like Musk and Dorsey as if they have a clue they know what they’re talking about. You can tell they have full confidence that they do, trapped in their bubble of fame.
Do you have examples of something decentralized that has stayed so and was not taken over by centralization or became highly bottlenecked or continued to work well?
Maybe, but that's just because of the scale of our population. By the same token, more people are considered starving today than there were people even alive just around 200 years ago.
Compare recently how the decentralized nature of the internet led to centralization of services.
