I think it takes a different kind of intelligence to be able to see through elaborate scams. You need more than just logic; you need to understand human psychology and the tricks these experts use to scam people.
Either Gavin did as he said and verified valid cryptographic proof, or he didn't. There's no psychology involved in that.
You have no proof that I'm not Satoshi either. Or that there isn't an invisible unicorn in my pocket.
You are correct. And so I can't state that you are NOT Satoshi, nor can I state that you ARE Satoshi (nor can I state anything about the contents of your pocket). What's the sense in even discussing it unless you're going to provide me proof?
I'm no crypto expert or con-man, I can't begin the imagine the types of tricks a scammer could use. But I'm sure there are plenty.
And if you want to nitpick like that, I haven't seen anyone say outright that "Craig Wright is not Satoshi". Certainly that's not what most people are saying. They're simply saying that it's highly unlikely that this guy is Satoshi, and I think that is a very reasonable conclusion based on the available evidence.
