Satoshi is not a single person. Satoshi is the "identity" of a billion-dollar multiple-year plan to have authority over ALL the money on the world.
How can Bitcoin give its creator authority over its users? The protocol is designed in such a way that you can only control your bitcoins if you know your private key.
Studies have shown that, on the average, Southeast Asians are about 10 IQ points above Western Europeans and Americans. The same studies have shown that spikes in IQ among Western Europeans and Americans are much higher and much more frequent than such spikes in Southeast Asians.
The point? There was probably one Southeast Asian person (Satoshi) who had a high IQ spike that was way above anything anyone else in the world has ever had (excluding Solomon in the Bible O.T., that is). This spike in IQ caused him to be able to build several virtually-invisible-to-the-rest-of-us back doors into the whole Bitcoin program, so that he could, if he wanted, immediately take control of the whole Bitcoin protocol everywhere, all at the same time.
The thing that Satoshi is doing now is quietly positioning Bitcoin throughout the world in such a way that it will collapse the banking system, unexpectedly, all at once. After the banking system collapses, when Bitcoin has become the dominant method for easy value transfer throughout the world, then Satoshi will take over the world.
I only hope he allows the rest of us who are Bitcoin adepts, to position ourselves near the top of the wealth before he takes over.
