World of decentralization

Bit torrent is just the tip of iceberg concept of decentralization, where any file is not hosted by particular server enterprise like say, this status photos videos are stored in facebook/google server (did you know that facebook sells each person data @25$ annually to analytics company).
In Bit torrent/ Aries (used to be hot back 6 years ago), things work differently, where files(software, videos etc) we want to download, are piece assembled from every different peers who have turned bit torrent on, on their machine (PC, smartphones, laptop) {I have not used term PC because PC is not only one that can participate in Internet of Things }. [Tron -cryptocurrency by Justin Drake blockchain-ify this bit torrent concept, which I do not precisely know details of but that is another day story]
Tada, bit torrent helps understand decentralized or peer to peer model but we are only getting started. Interplanetary File System (IPFS) hence is far more efficient to publish website than current HTTP model and has a few awaken community users.
Now, Vitalik has already pushed this peer to peer things even further by decentralized messsaging/communication protocol WHISPER (which I do not exactly know what it is), needless to say anything about ETHEREUM and decentralized storage system SWARM (yes, it is like IFPS). Developer community are undertaking its development and deployment. Vitalik's ETHEREUM VIRTUAL MACHINE (which means each and every IoT would make one giant computing storage system) or world computer would be soon completed. I dont know when.
