One effect doesn't exclude the other. I'm talking about people creating more problems than they are solving because they lack a fundamental understanding of how their systems, and the generated code that acts upon them, actually work. They're enamored with the ease and alacrity with which they can generate code but unwittingly leave a host of issues to be cleaned up. It's usually other people who discover the problems because these suddenly productive "authors" didn't have the know-how and awareness to create exacting enough prompts or sufficiently iterate on the generated output.
It's a phenomenon I've observed which doesn't necessarily take away from the benefits you've found. But maybe it's worth some consideration that this shift in empowerment isn't without negative consequences.
