I remember Yudowski being a thing like a decade ago, and people were making fun of his "AI" research even then. It's scary to realize that not only did some people take him seriously, but those people are at the helm of AI companies and making decisions affecting tens of billions of investment capital. I think there was a quote by Kurt Vonnegut that "true horror is waking up one morning and realizing your high school class is running the country".
For the other poster lower down, I'd almost successfully forgotten about his Harry Potter fanfiction, people kept praising it so I actually read through a bit of it, it's painful reading. He also wrote a Superman fanfiction and that's even worse. I think they both say a lot about his internal mental state and his perception of other people though.
