"Cryptocurrencies are an emergent property of the Internet – almost a fifth protocol in the Internet suite. If Satoshi Nakomoto did not exist, it would still be necessary to invent them. Someday, they will be used by the machines in our network, on our desk, in our garage, and in our pocket to exchange value and achieve consensus at blinding speeds, anonymously, and at minimal cost.
"When that day arrives, large distributed networks that we rely upon will change. Starting with the Internet, they will become de-centralized market economies, far more intelligent than they are today. Just as human brains co-evolved with our ability to trade and exchange goods with people who weren’t related to us, so the network will become more intelligent as it learns to trade currency and contracts with unrelated nodes."
