The Decentralization Revolution -
Philosophically, it is the next step in re-decentralizing the internet. A decentralized system is one that anyone can unilaterally join and participate in, one in which all participants contribute to the running and maintenance, and one in which any participant can unilaterally leave. When they do leave, the system continues regardless. In a decentralized system, there is no entity that can prevent participation or arbitrarily censor the content or usage. The internet was designed to be decentralized, but the way we use it has become increasingly centralized, to the point where censorship and exclusion are accepted and expected. Blockchain technology, introduced by Satoshi Nakamoto with the proof-of-concept implementation of a simple value transfer system known as bitcoin, represents the best digital system we have (after the internet itself) for administering multi-user interactions without any need for centralized coordination or oversight. Effectively, a decentralized system is its own authority for enforcing the rules (e.g. 'you can only spend your money once' in bitcoin, or 'whatever rule you programmed in to your smart contract' in Ethereum), so participants can be confident that the rules they expect to be enforced will be, without any danger of corruption, bribery, nepotism, political bias, exclusion, arbitrary exceptions, human oversight or absence of staff.
Ethereum allows people to safely interact trustlessly by entering into neutrally-enforceable agreements in a completely peer-to-peer fashion. Now, it must be remembered that Ethereum can only enforce within its own digital limits; Ethereum does not remove the need for an external authority for adjudication over disputes outside its realm---"the other party punched me in the face after putting in the Ethereum contract that he wouldn't" is non-sense, but rules exist elsewhere to cover this---but what Ethereum does do is allow us to push the boundary on what the digital realm can cover.
