Relays aren't truly redundant, but their data sets overlap, can be copied or mirrored, and the individual elements can be transported, discovered, and dispersed.

This means that we can store all of the world's data on one system without having to store it in one place or create n number of dataset clones that need to be constantly compared to one another. Related events will be stored nearer together on a relay, but also copied and stored in proximity to disparate events, that they are also related to.

Elements that are related to more things, or that seem more important to more npubs, will naturally have more copies. We can allow the data sets to evolve, just like genes and memes do.

This is data storage that mirrors the information and communication architecture of humans.

Just go with it.
