I have been seeing lots of community initiatives recently using blockchain; Bancor is doing a lot of work in Kenya and I know Akon is planning his own coin to help to communities out of poverty. Personally I think this is one of the best real-world use cases for blockchain, and one that we should see more of.

So we cannot just rely on new technology to try to resolve that problem, you also need the will of the people, you'll need the leaders of those countries to actually want to solve those problems, but they do not want to do that because they benefit greatly of the suffering of the people because they get more and more money thanks to it.
