I agree with your sentiments, except that I'd invert your sanity bitmap. I'd place John von Neumann as having been extraordinarily sane, and one of the most productive minds in history. I'd put Eliezer as far crazier and more potentially destructive than Kurzweil — there's not much distance between "creating survivable Singularities" and Butlerian Jihad. At least Kurzweil did productive things before he decided to live forever and tell us all about his magnificent future. Yudkowsky's brother died, and then he decided that nobody should have to die again.
