Linux actually got the "demons" right: those manifest as usually hidden activity in someone's brain, and in special circumstances can take control over the entire system (e.g. with a deadlock if it's a neutral demon, or by other means if it's malicious). Those Greek daemons, in contrast, never possess or control anyone: they may inspire, but only if the subject is consciously seeking such inspiration ("the gates must be opened from within").
