i'm quite sure there are people who know who Satoshi is. Nick Szabo and his early team definetely should know. it is also possible that Satoshi is one of them
Definitely a few people knows who satoshi nakamoto is. However, there arw speculation that it could be that satoshi nakamoto is not an individual person, but referring to a group of person. We actually don't know what the real thing is, but I think things are better just the way it is. If satoshi nakamoto's identity as known, and he dies, what do you think will happen to bitcoin, or how will this affect the market knowing that the genius behind it is gone and we cannot expect further genius development from it. So, let him be anonymous.
And thankfully, all these people are really smart but not as unbalanced as Craig Wright (who is also smart but probably a sociopath or unbalanced or simply just paranoid). Definitely not as hungry for cheap publicity either.
I don't think Nick Szabo knew or even Hal Finney, both were not Satoshi but both also probably respected the need for anonymity and never questioned it. But yeah, none of this is ever going to make an impact even if it was revealed today. Bitcoin is too strong to be affected at this juncture.
