Putt’s Law: “Technology is dominated by two types of people, those who understand what they do not manage and those who manage what they do not understand.”
Putt’s Corollary: “Every technical hierarchy, in time, develops a competence inversion.” with incompetence being “flushed out of the lower levels” of a technocratic hierarchy, ensuring that technically competent people remain directly in charge of the actual technology while those without technical competence move into management.
