Yudkowsky was it. If you go on less er... savory parts of the internet (read as Kiwi Farms/Encyclopedia Dramatica or any other forum ran by an edgy 15 year old on his mother's basement which I might not know of) and surprisingly you'll get an eye-opening biography on the guy from the late 90s from today. Dude's basically a cult leader. Just ignore all of the politics and the racism and you'll get the picture.
