Old people syntax hilighting

I've noticed that most of my professors don't use syntax hilighting in VIM. They will either use white on black, or green on black. Does /prog/ think that this makes them worse programmers?

Expert programmers write all their code on the back of napkins, like Leonardo da Vinci did.
If they have to read someone else's code, they first print it out on an old matrix printer. They use colored paper to group sections of the program, and highlight important parts and errors with a marker.
