This is very true, which begs the question - why was a 23-year-old summer intern placed in charge of the embassy computer system, or even given access to its central console? He may have have self-taught facility with computers, but I find it hard to believe he'd have much experience at that age with the sort of large, mission-critical institutional computer system described in the article.
I wonder if he had a supervisor sysadmin that he was working under, but given how he described his boss, that seems unlikely as well.
