How is it working? Who will host the terabytes of content is this really take off? Who will pay for it? Sure it’s easy to host a blockchain on a number of computers when it’s small, but if it really become THE source of truth, then you need actual $$$$$ to keep it alive.
I hope you still see this, it took me a few days to get back to you.

Those people [1], among others. You too, if you want. The great thing is that you don‘t need to store the entire weave to participate. If you store only 10TB, you will earn rewards at roughly 10TB/72TB = 1/7 efficiency.

Arweave has taken off, and the weave size is already above 72TB. [0]
> Who will pay for it?
The uploader. You pay for 200 years of storage AT CURRENT COST upfront. The trick is that this is not paid out immediately. Instead, an endowment is created, which pays for the continued storage over time.
Under the very conservative assumption that storage costs decrease by about 0.5% pa, this endowment will shrink over time, but never be exhausted (because storage gets cheaper over time). Essentially it is exponentially decaying. [2]
