It's not a technology problem, it's an incentive problem. Had the web somehow been centralized (I have no idea what that would even look like), content still would not be archived, it would be constantly changed, and subject to censorship. Just like in a decentralized web, perhaps even more so. Archiving costs lots of money (and costs keep growing if you only add and never take away), can be highly challenging (in the case of web apps or complex dependencies), whilst providing zero immediate reward for the organization carrying this heavy load. Not only is there no incentive, many couldn't even afford to if they wanted to. And it gets worse still. Digital archiving means paying forever. Imagine paying a 100 years of electricity, hardware replacements, migrations. The entity (business, person) is long gone before that. As a ridiculous example of this: Facebook has several very large idle content data centers. Mega scale buildings full of servers storing photos of Facebook users they haven't accessed in years, and likely never will again. Yet should a user do this, they expect the photo to still be there. That's why I believe the problem should be addressed with more pragmatism. Focus on things of unquestionable long term value, and think of a good solution for this smaller scope.
