Ah, I got to the bottom and the "Archetypes to avoid" section before realizing they weren't all cautionary tales, which makes more sense; while I grant that the absolute extremes should be viewed with some caution, I was trying to work out why ex. commitment to standards or going all-in on a microkernel would be bad.
Laughed out loud a few times reading about those oddly relatable archetypes.
