Also: - Economy of scale means this won't be "AirBnB for hosting". I can't negotiate power costs or get as much efficiency out of my operations as someone with a real datacenter. Not even close. [EDIT: see also, Bitcoin mining, which started out "anyone can do it!" but wasn't anymore as soon as real money got involved. Just buy an expensive rack of ASICs that aren't good for anything else, and find some place to arbitrage power costs. Yeah, real accessible to the masses, that is.] - All these "decentralize everything down to the end user" efforts neglect that most personal computing devices run on battery and sleep most of the time, these days, and that trend does not seem likely to reverse. See also: IPFS. Most folks don't have an always-on desktop- or server-class computer for this sort of thing, at all, and would have to buy one to participate. That's not super appealing. Also, decentralization tends to come at costs for routing and lookup, which often end up eating cycles (so, power, so, battery) on the end user's machine, compared with centralized options. See again: IPFS. So they end up adding centralized access points that are what most users actually interact with (see, yet again...) or their entire audience is computer nerds. If they have any real, viable use case, it ends up being as part of a centralized system, to help make it more resilient or cheaper to operate.
