I've just finished listening to another Internet radio interview about bitcoin, and although some mistakes should be expected, please avoid spreading the meme that Satoshi is a "world renown" cryptologist. He is not well known worldwide outside of this bitcoin community, and may not have training in cryptography.
Or rather, *nothing* is known about Satoshi outside of bitcoin, and most I've talked to believe it's a pseudonym.
I too was under the impression that Satoshi worked at a university somewhere due to his publishing of the bitcoin details in a paper. Most non-academic projects don't do this. When people said Satoshi was just a pseudonym, I was like "No way, there's a paper that lists all of his credentials, etc." and then when I checked I realized the only identifying information in that paper is his email, hosted at a free email provider. Searches based on that email yield only bitcoin-related results.
Ironically, he is now a world renowned cryptologist.
