AL Gore, the 45th vice-president of the US, said: "I think the fact that within the bitcoin universe an algorithm replaces the functions of the government is actually pretty cool. I am a big fan of bitcoin."
Similar effusive sentiments were expressed by several well-known (and well-meaning) commentators and influencers about bitcoin a few years back.
