Technology is cyclical just like business, the economy and the weather. The centralized/de-centralized technology cycle has been going on since the first "data processors". The move to the cloud was often touted as a return to "centralized computing". It should come as no surprise that there is already a decentralized computing model on the horizon. I'm not convinced "The Internet of Things" is necessarily it, but it is only a matter of time before the entire technological world returns to a decentralized model (after which another "centralized" model will eventually take its place).
