It is possible, that Satoshi is/are reading all these bitcointalk contributions ... and although some pepole want him/her/them to come back, nothing happened.
Tell one good reason why Satoshi should come back. (good reason = improvement of Bitcoin)
One good reason why he should come back is to tell everyone the intent and the purpose behind creating this great technology, Whitepaper does gives you a lot of details about why this was created but still listen to it from the person who created this system altogether would be a different experience. Secondly, he might be such a brilliant brain because he thought of something like this and this type of brain can be used in the future too to create some even better technologies or even solve the problems that layer 1 blockchains are today facing.
