Yeah it's really amazing that such information never leaked, even if you think that Blockchains would be a technology that demanded tons of programmers to make it...
It is very difficult to say who is Satoshi, whether is he is person or it is a group of organization which have formed this name and technology. Also I doubt anytime soon we will be knowing the original creator of this technology. Speculation could be high in form who will be the original person or organization who formed this.
At this point I believe he is just hiding his real identity for security measures, but why would someone try to attack him for creating such a wonderful thing tho?
