It's a question I'm asking because that is the claim that is being made. You should address this reply to those making the claim, not to the person questioning it.
EDIT: Also, please get out with the "owes you nothing" argument, I'm really growing sick of it. If I see something generating undeserved hype with potentially bad consequences for 'society at large', then I will damn well call it out. Don't like it, don't reply to it. It has precisely nothing to do with anybody owing me anything.
This is illogical, as evidenced by the illogical replies you are getting below. You are asking in a "serious" way for the IPFS community, developers or Juan to explain how all current use cases would work on IPFS.
That's a pretty tall order for an Open Source project that (seriously) owes you nothing.
I would suggest you attempt to run an IPFS node yourself and write a few applications and tell us how it goes.
