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.
there are a lot of different speculations about identity of satoshi and i think he is either dead or he is one of the bitcoin developers right now and we will never know his identity because he chose it to stay this way.
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?
the chance of that happening is less than the chance of me winning the lottery but i would freak out if i find out about him.
at first i am going to bombard him with questions about how he come up with bitcoin.
