I haven't read so much from what satoshi said back in the day but from the little amount I've read, he never came across as a attention craving shady old man like this dude seems to be.
Just curious, but how did everyone get the impression that he's attention craving? I watched the videos and read the articles/emails and I didn't get that.
What did he talk about at the conference? Everyone's been so busy discussing whether he's Satoshi or not that nobody has mentioned why he went. Did he speak about a new technical solution for a problem, or something mundane? If he's unknown then who invited him to speak, and why?
If he invited himself it suggests that perhaps he's attention craving, but if someone else invite him it suggests otherwise.
He talked about a wide range of topics, but he's also got at least 2 bitcoin related companies, and he has a supercomputer that has been modeling bitcoin scalability, not to mention that he's been a proponent for bitcoin since 2009 (publicly) so he's not a nobody and it's not hard to find a reason he might be on a panel.
