In a classic 1983 paper , cognitive psychologist Lisanne Bainbridge drew attention to a curious irony: so-called “automated” systems were, in practice, usually attended by one or more human operators. The more advanced the system, she observed, “the more crucial…the contribution of the human operator.”
