Where did it mention cultural fit? It seems that he skipped that, too. The one place I thought at first glance was referring to cultural fit:
> quite a few people are going to be really nice people that nevertheless aren't right for us
was actually just talking about being incapable of doing the job:
> If there's only one in two hundred resumes worth considering, quite a few people are going to be really nice people that nevertheless aren't right for us.
The mention of "ninja" programmers wasn't in respect to culture, either, but simply optimization.
