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?
I think that satoshi is not a single person but a mid or small team who worked and maybe still working for the bitcoin, I would ask him how much is your total amount of bitcoin holdings, what are your plans doing with them and where do you see bitcoin after 10 years.
