That's my opinion as well. But I doubt he is 85 years old. And I doubt Nick Szabo is his real name any more than Satoshi Nakamoto. Interesting the lack of any photos (I think I once saw a photo claimed to be of him, showing a mid-aged Caucasian male).

His website mentions giving at least one public address about ten years ago. It would be interesting if anyone can claim to have met him from his speaking events and could shed any light. My recollection is that his name does not match up with any Washington univ. faculty.
