PANews reported on October 8 that OpenAI CEO Sam Altman recently warned on Joe Rogan's blog that the US government is waging a "war" against cryptocurrencies and hopes to "control" Bitcoin. Sam Altman said: "I am very worried about how far state surveillance (implying state control over currency) can go. I am disappointed with the recent actions of the US government, but I think we cannot give up the war against cryptocurrencies, and we will control "Bitcoin and cryptocurrencies." I think the idea that we have a global currency that is not controlled by any government is a very logical and important step on the technology tree. Bitcoin is "most likely to become a universally viable currency."
