At very least, they can spare their storage to store this forum (since it's mostly about text) when they store at least 10PB of data[3].
It's though but, I thought about asking; how about the illustrative diagram/pictures and memes on important threads? I mean.... I know these pictures have already reduced quality - maybe about 100P of vertical resolution which consumes barely 250kb from the 10PB presumably...
Even with images, i'm sure it won't be problem for Internet Archive in terms of storage size.
* Is that going to be part of the storage problems we'll ever have in the future if we ever adopt a decentralized storage pattern?
Aside from what @larry_vw_1955 said, i expect many link to image no longer valid or can't be obtained without blocked by the image provider for requesting too many images.
* Since the transmission and regular update process will be way too slow, according to this quote, how do we regulate that to not go against our caches?
I simply don't know.
