My opinion is that, in reality, Satoshi Nakamoto might not have been who he said he was. Perhaps it was not one person and perhaps he carried out the mission that he was assigned to perform certain world forces. There is an opinion that this was a group of programmers. Maybe it was.
It doesn't really matter who satoshi really is; the only thing of importance is that Bitcoin is as real as it can be, and it's helping people obtain the freedom they otherwise would never have.
That's why I am glad he left and never came back again to bother with development. Don't get me wrong, my respect for him is sky high, but I'm pretty certain that at this point he would form a problematic factor for Bitcoin itself rather than a positive one. Ethereum is the perfect example of how lead developers not willing to part with their project are slowing down the rate of growth, and at the same time keep delaying scaling solutions as if it isn't that important.
Vitalik rolled back the chain with minority agreement, openly admitted to write hard forks if he's forced to do so, etc. No thanks.
