Is the Nick Szabo comment a joke, a guess, or for real?
He's been widely suspected as being Satoshi for years, its nothing new. I mean the similarities of Bitgold and BTC are uncanny.
Anyone could have
read about bitgold and been inspired to create Bitcoin. It doesn't have to be Szabo.
I've been told by someone who seems to know something that Szabo isn't Satoshi. Take that for what it's worth (not much, as presented).
Personally I rate Szabo as a likely candidate to have been involved in some manner. Some recent developments make that more likely IMO. No I won't elaborate. Do your own research. (It does not involve "john-connor".)
