Do you think it is reasonable to expect a person with an arts degree to know this?
Of course it is.
The only people who think your fucking college degree determines your knowledge level and ability are teenagers and people who are so deeply untalented that it’s the only way they feel qualified.
There are plenty of people with arts degrees who know this, and PLENTY of dogshit engineers with CS degrees who don’t
We've had a customer send us a prototype of what they wanted built with AI, and they don't have a college degree in anything. It followed our codebase patterns without any prompting, included tests, and all we had to do was wire up the backend.
Worth noting that you've slipped from "checking whether something works is easy" to "well, it's probably not as harmful as a very notable failure if it fucks up."
The bar lowers so quickly.
