The Satoshi protocol is about creating a mechanism to achieve distributed, trustless consensus. Plenty of applications for such a platform.
Whether it's achieving that goal is a separate debate (so far it has managed to establish itself as a crazy high risk forex medium that's only slightly less unwieldy than FIX) and I'm not convinced anyone in the builder space has even a vague understanding of the problems crypto has to overcome to be _practical_, let alone replace _the entire global financial system_.
Call me a pessimist but it's not gonna happen without violent revolution (and let's not please).
But we can stop saying vacuous things like "cryptography doesn't have a problem to solve", it's clearly always been about replacing trust with verification. Que KGB expression.
