I think anonymous Satoshi is indeed the best thing for this technology. But something always bothered me about Satoshi's anonymity. I think there is some kind of conspiracy here that makes Satoshi disappear forever. I think if Satoshi was really searched and traced with today's sophistication, I think it would definitely be possible to find out who the real Satoshi is.
If the identity of Satoshi isn't revealed, Bitcoin future will remain safe. And Bitcoin will be always fully decentralized because no one owns Bitcoin and controls the price. There is no conspiracy, Satoshi has planned it since the beginning to make it decentralized. If Satoshi continues to manage Bitcoin, it will be the same as altcoins. Anyway, it won't be easy to trace Satoshi because he left no evidence. I'm sure Satoshi is somewhere in this world, he isn't captured.
And I think Satoshi didn't work alone, I think the developers were a group of experts who dedicated themselves in their research. I think Satoshi was killed after they succeeded launching Bitcoin so no one can really claim to be Satoshi. But whoever he is and wherever he is, I am very grateful for this creation. He truly provides freedom in a world full of financial restraints and rulers.
We can assume there are some people behind the name of Satoshi. But it is just purely speculation, we can't claim it with no strong proof. You did a wrong thing to claim he is dead or killed. No evidence that tells us if Satoshi is dead already. Honestly, this is not so important anymore because Bitcoin can survive without the help of Satoshi anymore.
