This doesn’t match my experience. I needed a particularly boilerplate module the other day, for a test implementation of an API, so I asked Gemini to magic one up. It was fairly solid code; I’d have been impressed if it had come from a junior engineer. Unfortunately it had a hard-to-spot defect (an indentation error in an annotation, which the IDE didn’t catch on paste), and by the time I had finished tracking down the issue, I could have written the module myself. That doesn’t seem to me like a code quality improvement.
