1- AI-generated code just creates more technical debt.
2- At the end of the day, you (the developer) are responsible for the code, not the LLM that generated it. So the less code you have, the easier it is for you to own it.
3- A good engineer knows what code to write, and equally importantly, what code not to write or to delete.
(BTW, this is what we old-school software engineers have been saying for a long time, and we've been called all sorts of names for it.)
More AI-generated code doesn't make your team faster. It might actually slow you down.
