Is Satoshi Nakamoto dead?

I read that he has a million Bitcoin but hasn't touched any of them ever, it doesn't seem likely that when you are alive you would not tap into all of that wealth at some point. Also his internet presence disapeared in 2010.

One big question is how he has been able to hide his identity so well despite so many people wanting to know him and being dead before bitcoin ever became well known would be an easy explaination for that.

If he is dead rest in peace and thank you for creating Bitcoin.
