I firmly believe that Nick Szabo is Satoshi. Academic background, studies currencies, highly intelligent, worked on bitcoin-esque project before. Perhaps he had some help from a few close friends who do not know him as Satoshi.

But there are incentives to maintain it as a separate cover identity, of course. Ultimately I personally don’t give two fucks about who Satoshi is/was but the fact that it has become this central witchhunt and front page news has taught me a tremendous amount about brand building and the power and necessity of identity and narrative in our society and world.
