Technologies certainly can be replicated for other purposes. But the invention of bitcoin seems unique. It is less of an invention of technology than it is the invention of a computer network that we infuse real world energy into. There will only likely be one of those at a time. Because, why infuse energy into two systems if it could all be put into one, and everything built on that stronger foundation?
