For Karnofsky and to some extent Bostrom yes, Shulman is debatable, Yudkowsky tried to get screened (tried to write a programming language, for example, wrote a lot of articles on various topics, many of them wrong, tried to write technical papers (TDT), really badly), and failed to pass the screening by a very big margin. Entirely irrational arguments about 10% counter-factual impact of his are also a part of failure. Omohundro passed with flying colours (his PhD is almost entirely irrelevant at that point, as it is screened off by his accomplishments in AI).
