The question "Is BitCoin future-proof?" is a duplicate of the Stack Overflow question "Is bitcoin protocol future-proof?" with only a slightly different slant, and the same answer. How should inter-site duplication like this be addressed? Clearly, the question is on-topic here and probably would even have been asked here had this site existed at the time. But it also seems odd to copy an answer from another location on SE (even if it is my own!).
