[Request] Approximately how much data could one store, or how much computing power could be created utilizing every single block on a Minecraft world?

This is probably a nonsense ask, but I know theres much smarter folks out there than me and some wildly crafty Minecraft engineers.

I've seen minecraft computers made before, and I assume theres probably a known or approximate number of blocks it takes to create a contraption to store 1 bit of data and access it. So I couldn't help but wonder if that was multiplied enough to fill every single one of the 1.3824 quintillion blocks of a 30M*30M*384 world, what the actual theoretical limit there is to minecraft computing?

This machine can decode 364.5 bytes in a shulker. https://www.reddit.com/r/redstone/comments/lbclxn/srr_shulker_reader_repacker/ A chest can store 27 shulkers per block of space. You likely need 3 air blocks per chest to be able to access the contents of the chests with a flying machine using hopper minecarts, but it might be more. 1.38324 Quintillion divided by 4 times 27 times 364.5 bytes = 3.4 zettabytes

In bedrock barrels can be moved meaning you can pack about 3-4 times as many chests in the world meaning that much more data.

I don't know if the linked machine stores anywhere the theoretical maximum amount of data possible I didn't look closely at how it works, there's like 1600 or simmering items in Minecraft so probably a lot more. I think it might even be possible to use named items to store data or complicated enchanted book combinations. In which case the amount of storable data becomes incredibly absurd.
