Next-Generation Smart Contract and Decentralised Application Platform!
You may ask, "why would anyone use such a system?" and again there are many reasons. The main reason is because it makes what you want to do cheaper and easier. This statement needs to be broken down somewhat, which is what the following paragraphs explore.
Furthermore, as long as it is in demand, the Ethereum World Computer will always be there: it can't be shut down or turned off.
Ultimately, Ethereum could be used to run countries. Somewhere in between there are groups of people wanting to organize baby-sitting circles, film-making collectives, discussion groups, communal houses, etc, and they all have to decide the rules with which they will operate together.
Ethereum provides a platform on which rules can be defined and, to an ever increasing degree as technology improves, see enforced.
