Regardless of anything I would have more respect for anyone who didn't explicitly optimize the atomic bombs on Japan for civilian casualties like Neumann did.

Yudkowski is being derided because he wrote some weird fanfic which may or may not be problematic (I didn't read it, I dislike HP too much). And apparently "is considered a bit of a crank".

Neumann actually fucking did it, his calculations for maximum civilian casualties make him quite directly responsible.

I don't think you need to compare Turing, Wiener or Yudkowsky to that mass murderer.
