I think he or she will, something in my heart tells me they are still alive. I don`t think they will reveal their location or who they are, but I do think they will post on this forum in the next 5 years. It is only a matter of time before some big big rogue miners or bitcoin devs do something he or she do not like or see`s a problem with and they will have to come back and have a voice in the matter.
It will probably start by him or her saying something like this.
"Keep using the longest chain" or maybe "use this chain instead from now on"
I did a poll earlier a few months ago I think 19 out of 20 people said they would use whatever satoshi said.
I don't know. I see that some people believe that the guy who created it all is dead. Craig knew him, basically stole his contributions and now says he's Satoshi, even though it was more that guy, than him. I heard that the family of the deceased is accusing Craig of this, at least. But I do hope that the mastermind behind Bitcoin is still alive. And you're right when you write he/she, since even though most of people just assume it's a guy, it could well be a gal. In fact, a girl has an additional reason to hide identity, just like women did throughout history: so that the invention is not undermined because of the sexist views of those who use it. The bitcointalk account would be a good point for me, but then again it can probably be accessed by someone else who knows the real Satoshi but is not Satoshi. I bet Craig knows the real one, he's just too much of a d*ck to admit that it isn't him.
