That's part of the dangers of using them for software engineering. Writing more code does not make things better, just like hiring more devs does not make projects complete faster. I've already witnessed devs who are overwriting code for solutions, while at the same time some devs responsibly use it as needed.

It's literally the same pain point with low code solutions like WordPress page builders/plugins. Adding more becomes a hindrance, and even models with long context that can fit whole codebases will try to make up new functions that already exist. Just a couple weeks ago I had o3 continually try to write a new debounce function, even when I told it explicitly I had one.
