I'm not sure that's true. I think it's pretty tough for somebody who doesn't understand a field to assert that understanding the field deeper is not necessary.

I'm not sure that's true. I think it's pretty tough for somebody who doesn't understand a field to assert that understanding the field deeper is not necessary. You'll see many non-programmers assert that it's not necessary to get trained programmers to do a certain task (say, automation). However, they don't understand all the software engineering considerations and issues that you'll run into if you don't have a programming background. It's only when you truly understand a field that you can see when that field is applicable to the task at hand.
