Yes, I'm sure. I'm referring to scientific software - that is, software written in fields such as biology, chemistry, physics, and (non-computer) engineering. There are many grad students and professors in these areas who write software for their research that have no formal background in CS.
I wouldn't say they write software more than anything. I would say that there's a steadily increasing amount of time and energy invested into writing software, and very poor coding practices are used because of their lack of a formal grounding in CS and their short-term focus on obtaining the results necessary to publish their next paper and/or obtain their graduate degree.
That's like a classic scientist - software engineer argument. The scientist says he wants to prototype with quick dirty code while the software engineer wants to write great refactored code.
Yes, in those fields we literally "do write software more than anything" [else we do]. That is, most of what we're doing is writing software. So the fact that there's no formal training is a huge waste.
