Funny story time, intentionally vague to shield identities:

I have a friend who was hired to teach a course at a local University for their new CS degree that had a focus on video games some while ago. He was a bit of an expert in a particular portion of the material that they needed, and when they started putting out feelers to find someone to teach the subject matter, everyone locally in the industry gave him the highest praise and said he was the man for the job. The University met with him and eventually selected him to teach, which he did for 3 semesters. After 3 semesters, they dropped him because he didn't himself have a college degree in what he was teaching (which was something he made very clear in the hiring process.)

He went into making games straight out of high school, he was basically there at the ground floor, self taught, acknowledged by everyone in the industry locally as a foremost expert in the field where they had him teaching, and they couldn't keep him because they couldn't have him teach when he didn't have a degree in the field. Without his having a degree their program couldn't be accredited. So... They wanted him to have a degree in a subject he was an originator of and without that degree they had to drop him.

He makes financial software now because the games industry was/is brutal and he wanted to see his family now and then. I've always found it hilarious that a University had to let him go because otherwise the snake wasn't eating its own tail and the ouroboros apparently can't have that.
