Many individual CEVs are probably quite bad

I was thinking about Habryka's article on Putin's CEV, but I am posting my response here, because the original article is already 3 weeks old. I am not sure how exactly a person's CEV is defined. "If we knew everything and could self-modify" seems potentially sensitive to the precise chronological order of "realizing things" and "self-modification". Like, imagine Hitler getting the godlike powers of knowledge and self-control.
