there was a whole class of people who were scribes. That was their professional job

It is my understanding that these scribes wre responsible for biblical writings only. They were responsible for maintaining copies of scriptures. They weren't some olden day dictation service.

They weren't some olden day dictation service.

I don't know about in Paul's time but from what I've read about ancient Egypt that's exactly what they were.
