So, they reinvented torrents? Or old timers, do you remember the peer-to-peer connection from 90's called DC++ ( https://en.wikipedia.org/wiki/DC%2B%2B )? Like this IPFS, you'd connect to a hub (IPFS calls this a node) and get what people were sharing. This IPFS only takes that step a little further with hashing and distributing. Also, if this gets implemented widely, hash collision is going to be wild
It's reasonable to try again at the bigger goals now that there's more infrastructure / theoretical progress / audience.
