@e90m3 My father in law was a programmer at IBM and holds a phd in physics. We know his speciality was things that went to space, but he can’t/won’t talk about specifics. After that he taught programming at a university for 20 years.
He drove across country 5 years ago and had to call my wife at least three times to be walked through programming a Garmin gps and to be helped on multiple additional occasions when he accidentally changed it to a different language.
