In 2020, it feels positively archaic for me to edit office documents except in my browser and saved in the cloud, accessible anywhere.
Of course there's a bit of an inherent tension since there's really no such thing as a standardized open-source cloud to save to... which is why LibreOffice Online is "provide-your-own-filesystem".
But putting all the craziest ideas together in one jumble... has anyone ever seriously proposed something like distributed hash table cloud storage, extremely redundant, that was perhaps financed by a blockchain cryptocurrency operating on some kind of auction or supply-and-demand system, that could be used by open-source software?
So your storage would be virtually guaranteed always-available in a fully decentralized cloud, but with a financial incentive for people to contribute their own storage and CPU?
