I get the historical relevance and figurehead aspect, but to follow your example, nobody actually uses the early first computers (ENIAC, UNIVAC, Altair, etc.) anymore -- everyone today uses their improved descendants. Why hasn't the same happened in Crypto? Hasn't its functionality been pretty much superseded by later improved coins?
