I don't see that those consequences follow, at all. I see a natural evolution from where we are now to a world where people own their own servers in the cloud and run all the software on them.
Or, if you really don't want any data to go over the wire, just run all the web app servers locally.
There was a big swing from the idea that at&t would sell you a terminal that was connected to a central mainframe, to personal computers that were distributed, back to everything being centralized because the advantages of the web were compelling and centralizing things was the natural path. Things will swing back again to decentralization, but the difference this time is you will be able to access all of your data from anywhere at any time.
