OP here: Majority of professors became professors because there were very good at passing standard exam (and, TBH, some are not good at anything else).

I’m different because I was a bad student. Only managed to get my diploma with minimal grade, always rebel against everything. But some good people at my university thought that Open Source was really important and they needed someone with a good career in that field. I was that person (and I’m really thankful for offering that position)
