I retract my claim. Satoshi Nakamoto is definitely a human(or trying to act like one). A genius at that. He made two mistakes in his posts: walkthough and idealogical. So what if he had invented an A.I. with which he created a bitcoin. He would have obviously made mistakes or made inelegant code just to throw us off. How about that?

With this hypothesis, we can safely say self recursively improving A.I. existed since 2008/2009. But we have not found a way to make it. Whereas Satoshi made it and used it on his own accord. But then the question again is "Who is Satoshi?".

I would say a supernatural being in the garb of a human male with human lingo. He was trying to be relevant just to throw us off.

But why did he do it? Is it a part of the grand scheme of things? We may never know...
