No, Satoshi Nakamoto is not an AI or a group of people. No, he is a real human being and he is not dead.
Satoshi is writing a book, named 'The shape of bitcoin' explaining his motivations and disclosing many secrets we didn't know.
He will reveal his work ready to be published as a book if the funds in his genesis block address reach a valuation of 21 million US dollars.
He intends to give all this raised money to the charity 'GiveDirectly', based in Africa.
It seems Satoshi is antecipating being found and decided to surprise the world before that.
Satoshi is a great writer. Believe me.
