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.
this forum full of shit, very low quality information include to much scams and people even dont aware we have huge problem right now which need to be solved about scaling blockchain to hold huge amount of transaction per second for mass adaption while most people here even dont know this problem exist, while there are coins says they solved it which is strange while top experts still didnt found protocol data structure which solved this problem..
and what interesting you if satoshi is here or not or if he come back? the people behind bitcoin know where to reach and where quality information can be found and top discussion.
https://www.youtube.com/watch?v=Xoza4Fvk81M&t=535slisten in the beginning in this video .. this is where smart people discuss great ideas and share
people even dont know how much protocols out there and what the difference how data structure it self .. to speak about this here its like explain to someone when bitcoin was out and after 11 years most of the people here dont know shit.
