Satoshi is a real person. He is probably in his early forties. The problem with being an innovative thinker and filthy rich is that you get bored unless you're keeping yourself busy.
So, he is likely to be working somewhere in the technology world.
What if you accidentally figure out the guy you've been working with (sitting next to, is a customer, is a consultant, is your client, etc) is actually Satoshi.
What would you do?
Well, I'd say "Hello, Craig! Nobody believes you are Satoshi, but I do. You don't have to prove anything because it really doesn't matter who invented Bitcoin, but thank you mate, anyway."
Then he'd probably say: "You are crazy! Get away from me!"
And I would go my way. That'd be it. )
